The latest research results from IoT Newark developers reveal that 49% of respondents use AI in their IoT applications. There is also a growing concern about user privacy and the more frequent introduction of ready equipment.
35% of respondents think security is the major concern for any IoT implementation, mainly due to the type of data collected from the things (machines) and humans, which is very sensitive & personal. We can expect to see more and more encryption everywhere. Businesses who initiate IoT projects treat IoT security as their top priority.
SBC is still the preferred hardware foundation for IoT gates, then 54%, followed by personal projects (30%) and silicon supplier platforms (13%). It is unclear whether the latter includes a commercial computing module. As shown in the graph above, many IoT programmers need third party help, especially for edge-to-cloud communication.
About 45% of respondents use environmental sensors for IoT devices, followed by motion sensors (26%) and optical / image sensors (15%). WiFi (67%) is the most popular wireless technology in Internet of Things projects. The next places are Low cellular energy and Bluetooth, followed by LoRa at 21%. The survey results also include responses to programming languages, cloud platforms, IoT data, project motivation and more.
From the end of 2017 to 2018, artificial intelligence-specific processors (AI) began to appear on mobile devices. The goal is to make smartphones more intelligent. As GPUs shrink, AI-related equipment becomes necessary for the Internet of Things.
Support for enterprises from platforms such as Google TensorFlow will be introduced in 2020 with equipment adapted to artificial intelligence. TensorFlow is already optimized for mobile devices and can be quickly launched on single-board computers. In many ways, AI frameworks are better than other mobile frameworks, such as ReactJS. The AI structure is not designed to work with the user interface. It’s perfect for the Internet of Things.
Until the end of 2020, artificial intelligence will be as important for IoT devices as the cloud.

Aries Embedded announced one of the first computing modules with the SoF PolarFire function. It is equipped with a Linux RISC-V SoC chip with a Microchip Microsemi FPGA processor. The M100PFS has the same dimensions of 74 x 42 mm as the similar M100PF module from Aries and is equipped with PolarFire FPGAs without RISC-V core for Linux.
The two major M100PFS SKUs are:
M100PFS-025ADA0 — MPFS025T FPGA with 23K LE, 68 math blocks, 4x SERDES; 1GB LPDDR4 RAM for HMS (RISC-V/Linux); 4GB eMMC
M100PFS-250AECC — MPFS250T FPGA with 254K LE, 784 blocks, 16x SERDES; 4GB LPDDR4 each for HMS and FPGA; 8GB eMMC
PolarFire SoC from Microchip combines the previously introduced PolarFire FPGA card with 4x RISC-V U54-MC SiFive core. Microchip claims that PolarFire SoCs are superior to hybrid SoCs with an arm / FPGA, such as Xilinx Zynq, with more configurable and open RISC-V designs, lower power consumption and much better real-time deterministic functions. I am In December, the company called it „the first FPGA SoC chip with deterministic and consistent RISC-V processor clusters and the deterministic L2 memory subsystem enabling the use of Linux and real-time applications.”

Battery-ready IoT devices based on ESP32
Battery / SuperCap power support allows the processes and data to be securely executed, saved or transferred, and the operating system to be safely shutdown or reboot, if the power source has been restored. The power failure alert can also be sent to cloud service, to perform custom task, specified by user or self-learning AI algorithm.
The Moduino device is a comprehensive end-point controller for variety of sensors located throughout any installation. It fully supports temperature and humidity sensors and new ones are currently developed, e.g. accelerometer, gyroscope, magnetometer, etc.
Moduino–ModBerry symbiosis allows wide range of wake-up/sleep schedule customization, in order to perform best and save energy accordingly to power supply state. Arduino and MicroPython environments provide libraries to control different scenarios of data and power management.
With built-in algorithms and the possibility to program on your own, the TECHBASE’s sleep/wake addon module can wake the device using schedule/timer. Another option is wake on external trigger, e.g. change of input, etc. All the options for sleep, shutdown and wake can be configured for various scenarios to ensure constant operation of devices, safety of data and continuity of work in case of power failure in any installation.

Raspberry Pi devices are often used by scientists, especially for capturing and analyzing biological data. A particularly noteworthy sober project has published news this week.
According to the researchers at UMass Amherst, FluSense is about the size of a dictionary. Includes an inexpensive microphone set, heat sensor, Raspberry Pi and Intel Movidius 2 neural engine. The idea is to use AI on the edge to classify audio samples and determine the number of people in a room at any given time.

We believe that FluSense has the potential to expand the arsenal of health surveillance tools used to forecast seasonal flu and other viral respiratory outbreaks, such as the COVID-19 pandemic or SARS,” Rahman told TechCrunch. “By understanding the ebb and flow of the symptoms dynamics across different locations, we can have a better understanding of the severity of a novel infectious disease and that way we can enforce targeted public health intervention such as social distancing or vaccination.
The device distinguishes cough from other sounds. By combining cough data with information about the size of the crowd at your location, you can get an index that predicts the number of people who may be experiencing flu symptoms.
Currently we are planning to deploy the FluSense system in several large public spaces (e.g., large cafeteria, classroom, dormitories, gymnasium, auditorium) to capture syndromic signals from a broad range of people who live in a certain town or city,” they said. “We are also looking for funding to run a large-scale multi-city trial. In the meantime, we are also diversifying our sensing capability by extending FluSense’s capability to capture more syndromic signals (e.g., recently we added sneeze sensing capability to FluSense). We definitely see a significant level of commercialization potential in this line of research.

The Raspberry Pi platform, with introduced in 2019 Raspberry Pi 4 is no longer available with lowest, 1GB RAM configuration. Since the price of 2GB version dropped by $10 to the $35 — the same as the 1GB version. Therefore the 1GB is no longer available for puchase. Also the USB type C problems were fixed with the latest revision.
In latest announcement, Eben Upton, co-founder and CEO of Raspberry Pi Trading, admitted that most people already know that Raspberry Pi 4 requires at least 2 GB of RAM to be the first Pi to replace desktop computers. Upton also says, that comared to original original Raspberry Pi, the new RPI 4 has 40x processor performance, 10x bandwidth and 4x screen pixels. The SBC also has 4 to 8 times more RAM than the previous 512 MB model.
Raspberry Pi increase in IoT significance
More and more engineers and technology providers believe that it is suitable for industrial applications in the real world. Over the past few years, there has been a lot of discussion about the use of Raspberry Pi in industry, most of which emphasize that Raspberry Pi is a great tool for engineering experiments, but not so much for industrial applications in the real world. While it is true that the Raspberry Pi is not considered the best choice for mission-critical applications, it is also true that the Raspberry Pi is no longer a platform for experimentation.
Latest Raspberry Pi 4 development board, equipped with a 1.5GHz quad-core 64-bit ARM Cortex-A72 processor (approximately 3 times better performance than previous Cortex-A53 powering Raspberry Pi 3+ Model B and Compute Module 3 and 3+). can be chosen from 1GB / 2GB / 4GB LPDDR4 SDRAM options.
Raspberry Pi 4, with 2xHDMI, Gigabit Ethernet and 2xUSB3.0
Raspberry Pi 4 continues the tradition of one of the most versatile and cheapest computer devices. It can be used for virtually anything from proprietary IoT solutions to a full-fledged desktop computer. The new Malinka has two micro-HDMI ports, a Gigabit Ethernet port, two USB 3.0 type A ports and two USB 2.0 type A ports.
Industrial use of Raspberry Pi 4
A year ago, TECHBASE released an updated version of the ModBerry M500 industrial IoT computer, replacing the aging Raspberry Pi 3 with a 3B+, giving it better performance. With the recent launch of the Raspberry Pi 4, TECHBASE has yet again, announced another upgrade to the M500, which now packs the latest single-board computer.
Over 10 million Raspberry Pi’s have been sold and the Raspberry Pi is likely to stay as a new standard in the industry. Official Raspbian OS is free operating system based on Linux Debian optimized for the Raspberry Pi comes with over 35,000 packages, pre-compiled software bundled in a nice format for easy installation. ModBerry devices are compatible with Raspberry Pi accessories, supported by Raspberry Pi Foundation. ModBerry M500 now with Raspberry Pi 3 Model B+ / Raspberry Pi 4 Model B support.

UPDATE 22.10.20: ModBerry 500, first industrial computer based on Compute Module 4, available for pre-order
TECHBASE’s ModBerry industrial computer series has received an update to Compute Module 4 and is available for pre-orders. TECHBASE is leading manufacturer of Industrial Raspberry Pi and Industrial Compute Module solutions. ModBerry 500 series is fully compatible with all releases of Compute Module from Rasbperry Pi foundation.
Main features of updated device are:
up to 4x faster eMMC Flash with up to 32GB storage
up to 2x faster performance of CPU apllications than previous CM3 version
up to 8x more RAM (8GB LPDDR4)
optional 1Gbit Ethernet interface

Update on Raspberry Pi’s Compute Module 4 features [15.10.2020]
According to latest leaks about Compute Module 4 specifiaction and features we can be more than sure that:
New Compute Module will feature Wi-Fi and Bluetooth on-board! Raspberry Pi Compute Module series will probably include versions with and without these modems to provide modules for variety of industrial applications.
PCI-Express line will be available externally to enable extension support via PCIe
Ethernet support will be enabled, most probably 1Gbps, since it is a standard in latest Raspberry Pi 4B.
Compute Module 4 a new milestione in Industrial IoT
A new milestone of Industrial IoT might come to life in this year. The successor of Raspberry Pi Compute Module 3+, working named Compute Module 4, will certainly draw from Raspberry Pi 4 B features, such as new Cortex-A72 processor (Broadcom BCM2711) and multiple RAM/eMMC options. Rumours say, that we may also see Gigabit Ethernet and USB3.0/3.1 support, since it was a main drawback in previous models.
Raspberry Pi release timeline with probable Compute Module 4 release date
First Rasbperry Pi 1B model had it’s analogy in industrial Compute Module 1 after almost 2 years from it’s premiere. Compute Module 2 was probably omitted because the change from RPi1 to RPI2 mainly involved a minor change of the processor (Cortex-A7 900MHz), which was almost immediately replaced with Cortex-A53 1.2GHz in Raspberry Pi 3.
The premiere of Compute Module 3 occured a year after RPI 3 announcement, providing a significant boost of industrial market solutions. Since Raspberry Pi 4 was a great success in 2019, we might see it’s equivalent in industrial series of Raspberry Pi – Compute Module 4. A possible release date of Raspberry Pi’s Compute Module 4 is mid-2020.
Raspberry Pi is gaining recognition in Industry
Almost a year ago, in the beginning of 2019, Raspberry Pi Foundation presented Raspberry Pi Compute Module 3+, a successor to previous CM3 version of development board, aimed at businesses and industrial users. The Compute Module uses a standard DDR2 SODIMM (small outline dual in-line memory module) form factor. GPIO and other I/O functions are routed through the 200 pins on the board.
Raspberry Pi Compute Module 3+
Only a few months later, in June 2019, came big premiere of Raspberry Pi 4 Model B, the long-awaited successor of customer RPi3+. With new processor, larger RAM options and many input/output changes, became new standard in small, embedded PC world.
It seems a matter of time before the Raspberry Pi Compute Module 3+ will get its own successor, probably called Compute Module 4, a new milestone of professional embedded IoT module. What might be the specification of this highly expected development board?
Raspberry Pi Compute Module 4 specification forecast
Compute Module 4 specifications probably will look like these:
and OpenGL ES 3.0 graphics will replace 1.1, 2.0 versions,
weight and factor will stay the same, to provide a possibility to upgrade current IoT applications of CM3 and CM3+
A Lite 4 version of Compute Module is to be expected too, without eMMC and probably limited SDRAM options.
With much higher performance, the new Raspberry Pi Compute Module 4 will, for sure, support Gigabit Ethernet, USB 3.0 expansions. We might even see wider working temperature range, if Raspberry Pi Foundation decides to make some hardware changes, to follow, for example, ESP32 – used in end-point IoT automation.
Industrial use of Compute Module
With Compute Module 3+ options from Raspberry Pi, TECHBASE upgraded their ModBerry 500/9500 industrial computers. From now on the ModBerry 500/9500 can be supported with extended eMMC, up to 32GB. Higher memory volume brings new features available for ModBerry series.
ModBerry 500 with Compute Module 3+
Higher performance of ModBerry 500/9500with extended eMMC flash memory, up to 32GB , powered by quad-core Cortex A53 processor allows the device to smoothly run Windows 10 IoT Core system, opening up many possibilities for data management, remote control and visualisation.

First major announcement is that Sigfox will launch a private network (PAN) that will allow IoT customers to choose private and global services according to their needs. The service will be launched for the first time in France in the first quarter of 2020, but Sigfox will be implemented in over 65 countries.
The operator’s wide area network (WAN) will be completed next year in cooperation with Eutelsat. Sigfox provides coverage worldwide using the nano-satellite constellation launched by Eutelsat.
The Sigfox PAN offer will benefit from the existing Sigfox WAN ecosystem. Thanks to the potential to use all components on the market and the use of very low transmit power to support facilities without the need for batteries, the Sigfox PAN offer offers enormous potential,
Ludovic Le Moan, CEO and co-founder of Sigfox.
According to Sigfox, by the end of 2019, there will be more than 15 million registered facilities and over 1,500 customers using this solution in various industries around the world. Sigfox says that PAN customers can expect the same as WAN customers in terms of support and quality. PAN clients can choose to subscribe to additional „WAN Extension” services if needed if the device needs to communicate outside the local network.
Sigfox improving the accuracy of Atlas geolocation services
Internet of Things operators have now launched Atlas Native Complimentary. It is made available free of charge in exchange for the rights to process data regarding GPS data. These data are compared to the fingerprint of the Sigfox network using machine learning, which increases accuracy to 800 meters.
To further increase the accuracy of its geolocation services, Sigfox said it has completed the global implementation of Atlas WiFi in collaboration with HERE Technologies’ mapping experts.
Sigfox uses the global WiFi access point database here. Access points are checked by the Sigfox WiFi tracking module and more closely track the location of external and internal resources with less battery consumption than using GPS.
We are delighted to strengthen our partnership with Amadeus and share our combined expertise to create real digital transformation of the travel sector. Our strategic alliance named PinPoint will not only help to improve the travel experience, but this will also change completely the game for an industry looking for decades for THE technology able to save costs while improving efficiency and quality of services
Raouti Chehih, Chief Adoption Officer at Sigfox
The first services from the strategic alliance are expected to hit the market in 2020.
Industrial use of ESP32-based solutions
One of industrial IoT devices, supporting Sigfox wireless technology is eModGATE from TECHBASE. Economical, ESP32-based solution can serve as an end-point in any installation or works well as a gateway, gathering data from scattered sensor mesh across the installation.

At the end of last week, Linus Torvalds brought a complete list of Linux 5.5 changes for ARM, MIPS and RISC-V architectures. Io_uring asynchronous I/O has been improved, adding the ability to modify the set of files being operated on without starting over, user-specifiable completion-ring sizes, absolute timeouts, and support for accept() calls among others.
Also the Airtime Queue Limits (AQL) for WiFi that make CoDel work more effectively with wireless drivers that utilized firmware/hardware offloading. KUnit unit testing framework for the Linux kernel with tests can now be run locally on a developer’s workstation without any VM or special hardware. Another change is SMB rootfs and multichannel support using SMB as root file systems, and support for using multiple network connections for the same SMB session.
So this last week was pretty quiet, and while we had a late network update with some (mainly iwl wireless) network driver and netfilter module loading fixes, David didn’t think that warranted another -rc. And outside of that, it’s really been very quiet indeed – there’s a panfrost driver update too, but again it didn’t really seem to make sense to delay the final release by another week.
Outside of those, it’s all really tiny, even if some of those tiny changes touched some core files.
So despite the slight worry that the holidays might have affected the schedule, 5.5 ended up with the regular rc cadence and is out now.
That means that the merge window for 5.6 will open tomorrow, and I already have a couple of pull requests pending. The timing for this next merge window isn’t optimal for me – I have some travel and other things going on during the same two weeks, but hopefully it won’t be all that noticeable. But there might be random timezones, odd hours, and random delays because of that. I try to avoid scheduling things during the merge window, but hey, it doesn’t always work out, and I’d have to delay things by two weeks to avoid the conflicts, which just doesn’t seem worth it.
Particularly since it’s not necessarily going to be a problem to begin with. We’ll see.
Anyway. Go out and test 5.5, and start sending me those pull requests for all the new development that is ready,
With 19.10 release of Ubuntu Server, Canonical announced official support for the Raspberry Pi 4.

Good news for developers and modders of router software. A new Linux distribution, OpenWRT 19.07 has just been released, created primarily for WLAN devices, which debuted with the iconic Linksys WRT54G routers. OpenWrt 19.07 is mainly developed for devices using the AVR32, ARM, CRIS, m68k, MIPS, PowerPC, SPARC, SuperH, Ubicom32, x86 and x86-64 architecture.
What’s new in OpenWrt 19.07
A lot changed from the previous version of OpenWrt 18.06 version. Even WPA3 support has been added. However, it is not enabled by default and requires the installation of additional packages.Hostapd-openssl is needed for WPA3 to work in access point mode, it will need wpa-supplicant-openssl or wpad-openssl (additional AP) to use in Wi-Fi station mode.
Software developers have decided to switch to ath79 from ar71xx – in the future support for ar71xx will be completely withdrawn. In addition, the Linux kernel has been updated to version 4.14.162, and support for adm5120, adm8668, ar7, au1000, ixp4xx, mcs814x, omap24xx, ppc40x, ppc44x and xburst has been terminated.
A new feature is the updated LuCI, an integrated web interface for OpenWRT that implements client-side rendering. The LuCI ecosystem is large and not all LuCI applications have been adapted for this change, which can cause cbi.lua crashes. If so, install the luci-compat package.
The latest version of software can be downloaded from the project’s official website, here where you can also find the full list of changes.
Why should you try OpenWRT?
People who like to modify soft routers will confirm: OpenWRT dramatically increases the capabilities of network devices. OpenWRT is several thousand software packages that advanced users can install or remove depending on their needs. The software also improves network security – after all, the router owner will have full control over the configuration of every aspect of the hardware.
Industrial use of OpenWRT-based solutions
One of industrial IoT devices, supporting the technology and it’s varieties is ModBerry M series from TECHBASE. Economical, M300 model, based on NanoPi boards can serve as an OpenWRT modem, with optional changes in standard ModBerry controller.
