Raspberry Pi Compute Module 4 with PCie/NVMe next year

In recent interview with Eben Upton, the CEO of Raspberry Pi Trading, we finally had Raspberry Pi Compute Module 4 release confirmation, probably in 2021. He shared some details about the upcoming CM4 features, such as single-lane NVMe support.

The Raspberry Pi Compute Module, CM4, we will support NVMe to some degree on that,  because of course, it [Raspberry Pi 4] has a PCI Express channel. (…) We have a single lane Gen 2 which is used to supply USB 3.0 on the Raspberry Pi [4]. On the [Compute] Module that would be exposed to the edge connector and we’re likely to support NVMe over that.

Eben Upton, CEO of Raspberry Pi Trading

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 somewhere inbetween 2020/2021.

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.

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 PCIe/NVMe support, CM4 might be a black horse of industrial automation in 2021.

It seems a matter of time before the Raspberry Pi Compute Module 3+ will get its own successor, 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 probable specification

Compute Module 4 specifications probably will look like these:

  • Broadcom BCM2711, Quad core Cortex-A72 @ 1.5GHz will highly plausible replace previous Broadcom BCM2837B0, Cortex-A53 64-bit SoC @ 1.2GHz,
  • 1GB, 2GB or 4GB LPDDR4-3200 SDRAM will become a standard options, instead of fixed 1GB LPDDR2 SDRAM,
  • PCIe/NVMe support via single lane
  • Current flash memory (eMMC) options: 8GB / 16GB / 32GB from CM3+ will probably stay the same,
  • weight and factor will stay the same, to provide a possibility to upgrade current IoT applications of CM3 and CM3+

With much higher performance, the new Raspberry Pi Compute Module 4 will, for sure, support Gigabit Ethernet, USB 3.0 expansions with PCIe/NVMe single lane. 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. Upcoming Raspberry Pi’s Compute Module 4 will be fully compatible with TECHBASE’s ModBerry 500/9500 controllers, oferring extended features.

Arduino or Raspberry Pi? Pros and cons in IoT use.

Arduino or Raspberry Pi? Pros and cons in IoT use.

Some people consider the Arduino platform to be the best for beginners, however, the novice will handle both Arduino and Raspberry Pi board. The choice between platforms should mainly depend on the characteristics of the project.

The origin of both platfoms

The founder of Arduino is Massimo Banzi, a lecturer at the now-defunct Italian Interaction Design Institute Ivrea, who developed a microcontroller in cooperation with students from this university. The Arduino programming language, based on the Wiring environment and basically on the C/C++ language, was designed by Hernando Barragán, a student of Banzi. The site prepared by Hernando Barragán presents exactly all the work on the project, which clearly shows that this success has more than one father.

  • Raspberry Pi 4
Raspberry Pi 4 (left) vs Arduino Uno (right)

In the case of Rasberry Pi, the project also had its source at the university. More specifically, at the University of Cambridge. Three lecturers: Jack Lang, Alan Mycroft and Robert Mullins came up with the idea of ​​developing a simple and above all cheap computer for learning programming. The first prototypes were created between 2006 and 2008. In the next step, seeing the potential of their solution, the men established cooperation with Pete Lamas, an integrated circuit designer at BroadCom, and David Braben, one of the developers of the Elite game, and together they founded the Raspberry Pi Foundation.

As a result, both platforms, which were originally intended to be used for learning by students, due to their low price and simplicity of use, became extremely popular among amateur users of consumer electronics and control, and appeared in mass sales.

So what should you choose – Arduino or Raspberry Pi?

The answer is basically simple – Arduino is ideal for simpler projects. Raspberry Pi will be useful for solutions that require more computing power. Arduino has only 2 kilobytes of RAM. Raspberry Pi has a RAM size of 1 GB. So Arduino is a simple microcontroller, meanwhile Raspberry is actually a small computer. Not without significance is the fact that the Arduino IDE is easier to use than Linux. So if you need a simple control of watering your garden, Arduino will work perfectly. Several sensors and a few lines of code will do the trick. For Raspberry Pi, to achieve the same effect, you will first need to install the system and the necessary libraries. There will be a lot more work and the effect will be the same – watering the garden at a specific time.

So choose Arduino when you need to use a simple solution for frequently repeated activities, e.g. controlling the watering of the garden, switching on and off the external lighting at a specific time, opening the gate, etc. However, because Raspberry can run many tasks at the same time, it is a computer, work simultaneously as a home printer server and operate the monitoring system. Home weather stations are popular and Raspberry will be perfect for this application because of the need to collect information from several sensors (temperature, wind strength, humidity). Raspberry Pi will therefore be a good choice for anyone interested in IoT, i.e. the Internet of Things at home. Examples of ready projects can be found here: https://modberry.techbase.eu/

  • eModGATE with ESP32
  • ModBerry 500 with Raspberry Pi’s Compute Module 3+
On the left: eModGATE powered with ESP32 (Arduino based)
On the right: ModBerry device powered with Raspberry Pi Compute Module 3+

Why not both?

Nothing prevents you from starting with Arduino and continuing with Raspberry Pi. By using Arduino or ESP32-based solutions you will learn the basics and you will get the effect quickly and relatively easily. But only Rasbperry Pi will allow you to make much more difficult projects. And both platforms can be combined with each other. Arduino/ESP32 can be used to read information from sensors and control e.g. motors (for example a garage door). Raspberry Pi will control all devices and send the collected data, e.g. to a mobile phone. You can do more together.

LoRa vs NarrowBand-IoT. What is better for Industrial IoT?

LoRa vs NarrowBand-IoT. What is better for Industrial IoT?

Low-power wide-area (LPWA) technology meets the needs of multiple IoT markets for low-cost devices that maintain long battery life and low-cost, large-area networks that support large numbers of connections. However, LoRa (LoRaWAN) and NarrowBand-IoT have the most momentum and will gain the largest share in the LPWA market in the next few years.

Many technology articles compare LoRa and NB-IoT technologies as if they were battling it out for dominance in the IoT market. In reality, these technologies are two branches within an emerging technology ecosystem. Similar to WiFi and Bluetooth, they will most likely to diverge into different niches, rather than directly compete with each other. This article will dive deeper into the capabilities, costs, longevity, maturity, and other differentiators of NB-IoT and LoRa-based technology.

Sigfox/LoRa and NB-IoT in direct comparison

As a result of the research, performed by Tauron, it was found that SigFox and LoRaWAN technologies have limited applications due to the use of the unlicensed ISM band (868 MHz). In addition, each of the three technologies tested has a limit on the transmission channel speed. LoRaWAN, unlike others, allows the construction of an autonomous, separate network dedicated to the needs of the owner.

Source: https://lora-alliance.org/

LTE NarrowBand-IoT technology, as a 3GPP standard, is being increasingly implemented by subsequent mobile operators in the world and in European countries like Poland. For example, polish main frequencies of NB-IoT implementation are 800 MHz and 900 MHz, which allows achieving high coverage of the country.

Research carried out by Tauron has shown that, considering the security of the solution, the availability of telecommunications infrastructure, or the speed of data transmission (important for meter reading), LTE NB IoT technology is closest to use in the energy sector.

Both LoRa and NB-IoT standards were developed to improve security, power efficiency, and interoperability for IoT devices. Each features bidirectional communication (meaning the network can send data to the IoT device, and the IoT device can send data back), and both are designed to scale well, from a few devices to millions of devices.

Use of LoRa/NB-IoT in industrial automation

Use of wireless connection makes life and work easier for us every day – from radio stations and GSM to Wi-Fi wireless networks, Zigbee, short-range Bluetooth connectivity and LoRa / NarrowBand-IoT wireless solutions. With the spread of internet access, the possibility of using wireless connectivity for a new type of service and application has opened.

ModBerry 500 / ModBerry 9500

Device equipped with LoRa module is delivered with a LoRaWAN protocol stack, so it can be easily connected to the existing, fast-growing LoRa Alliance infrastructure – both in privately managed local area networks (LAN) and public telecommunications networks to create wide area low power WAN (LPWAN) on a national scale. LoRaWAN stack integration also allows connection to any microcontroller, such as ModBerry industrial device from TECHBASE. Such solutions offer also NarrowBand-IoT and full 4G/LTE support.

Raspberry Pi in the service of COVID-19 monitoring

Raspberry Pi in the service of COVID-19 monitoring

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.

Crowd monitoring with Raspberry Pi

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.

How Raspberry Pi Compute Module 4 (BCM2711) might help IoT & Industrial Automation?

How Raspberry Pi Compute Module 4 might help IoT & Industrial Automation?

It a matter of time before we will see Raspberry Pi Compute Module 3+ 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? What changes will it bring to Industrial use of IoT?

Compute Module & Industrial IoT symbiosis

We are witnessing the fourth industrial revolution. Its key element is to create systems of interconnected sensors and actuators that operate within one global network. The so-called Internet of Things, unlike the consumer market, meet much more difficult requirements. To be able to meet harsh industrial expectations, many automation companies have already begun to offer solutions especially tailored to the application of the Internet of Things in Industry 4.0.

Although it may seem quite obvious nowadays, it is worth to be aware that just a few years ago such algorithms were practically not implemented at all in small consumer devices. It was only when people got used to smartphones that the idea of ubiquitous communication and adaptation of the way the system or device works to the environment became understandable. In fact, this confirms the validity of the idea of the Internet of Things as an important direction in the development of electronics – and in practice also automation.
