TECHBASE’s Industrial IoT Ecosystem gives the opportunity to adjust ordered devices with certain resources and cut unnecessary I/Os, lowering the total cost of the device. 

Raspberry Pi Compute Module 4 Cluster

Reason for use of Raspberry Pi CM4 cluster in ClusBerry 9500-CM4

Various implementations must have guaranteed high hardware performance to react fast enough in real time. For this purpose, the arrays of processor blocks are constructed to be assigned to individual tasks. For several years now, attempts have been made to use various types of SBC for this purpose, including, of course, Raspberry Pi. However, the practical effectiveness of such solutions so far has not been of interest for several reasons. First of all, these solutions were most often associated with many mechanical limitations and the structure of the matrix itself required excessive wiring, preventing failure-free operation and the cost of the entire maintenance of the structure.

Raspberry Pi Compute Module 4 Cluster

This is where Raspberry Pi Compute Module can shine, but due to the hardware speed limitations of the buses in this module, it was not completely effective and was rather a development platform. Altho the introduction of new Compute Module 4 has opened the possibility to construct and maintain effective hardware matrix solutions with the use of both PCI-Express buses and 1GBps Ethernet. Therefore, the ClusBerry 9500-CM4 opens up completely new capabilities of utilizing cluster solutions for Industrial Automation and server applications.

Wide range of ClusBerry modules

With use of Docker-based and Kubernetes solutions, installation and management of ClusBerry 9500-CM4 is easy and backed with a large community for further support and development. Kubernetes is a portable, extensible open-source software platform for managing containerized tasks and sites that enables declarative configuration and automation. The Kubernetes ecosystem is large and dynamically developing. Kubernetes services, support and tools are widely available.

Kubernetes provides:

  • Detection of new services and traffic. Kubernetes can balance the load and redirect the network traffic to ensure the stability of the entire installation.
  • Kubernetes data storage management enables you to automatically mount any type of storage system – on-premises, from cloud providers and others.
  • Automatic deployment and rollback. You can describe the expected state of your installation with Kubernetes, which will take care of bringing the actual state to the expected state in a controlled manner. For example, with Kubernetes, you can manage your cluster modules at ease, boot modules from one to another, upgrade firmware crosswise and provide safe operation of each module
  • Automatic management of available resources. ClusBerry 9500-CM4 provides a cluster of modules that Kubernetes can use to run tasks in containers. You determine the CPU power and RAM requirements for each container. Kubernetes arranges containers on machines in such a way as to make the best use of provided resources.
  • Self-healing Kubernetes reboots containers that have stopped working, replaces them with new ones, forces disabling containers that are not responding to certain status queries, and does not announce their availability until they are ready to run.
  • Managing confidential information and Kubernetes configuration with TPM Security Chip allows you to store and manage confidential information such as passwords, OAuth tokens and SSH keys. Secured data and configuration information can be provided and changed without having to rebuild the container image and without exposing sensitive data in the overall software configuration.

Industrial use of market Banana Pi-like SBCs

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.

ModBerry M500 with Raspberry Pi’s 4

ModBerry M500 also utilizes many more SBC platforms, such as Orange Pi, NanoPi and Intel-based UpBoard. Find more information here: https://iiot-shop.com/product/modberry-m-series/

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.

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/

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.

Every fan of new technologies has heard of small single-board computers (SBC) in the form of Raspberry Pi 4. Raspberry debuted on the market in many different versions, and the current model is Model 4B. A lot of people got infected with it for DIY, programming or Linux. But new board comes with variety of pros and cons, as compared to previous RPi3 versions.

Nowadays, mobile Internet offers are becoming more and more popular. They are often cost-effective for those who do not download too much from the web. Usually you don’t even need to sign a contract – some operators offer fairly favorable pre-paid internet offers. Anyway, even if we want an Internet contract, sometimes the monthly fee is lower if we do not take the device.

In that case, how will we receive this Internet? The solution is simple – unfortunately we have to invest some money in the LTE modem. As a router separating the signal we will use Raspberry Pi. For a ready and complete solution we can choose ModBerry Industrial IoT devices already equipped with modem of our choosing

ModBerry M500 modem configurability

ModBerry M500 added wide range of I/Os to the board, including RS232/485 serial ports, digital and analog I/Os, 10/100Mbps Ethernet port, USB, 1-Wire and optional CAN.

Linus Torvalds released Linux 5.7 with this announcement:

So we had a fairly calm last week, with nothing really screaming “let’s delay one more rc”. Knock wood – let’s hope we don’t have anything silly lurking this time, like the last-minute wifi regression we had in 5.6..

But embarrassing regressions last time notwithstanding, it all looks fine. And most of the discussion I’ve seen the last week or two has been about upcoming features, so the merge window is now open  and I’ll start processing pull requests tomorrow as usual. But in the meantime, please give this a whirl.

We’ve got a lot of changes in 5.7 as usual (all the stats look normal – but “normal” for us obviously pretty big and means “almost 14 thousand non-merge commits all over, from close to two thousand developers”), So the appended shortlog is only the small stuff that came in this last week since rc7.

Go test,

Linux 5.7.1 changes from 5.7

  • New, higher-quality exFAT file system from Samsung replacing the exFAT implementation added to Linux 5.4.
  • Thermal Pressure in the task scheduler – Thermal Pressure makes the task scheduler more aware of frequency capping, and leads to better task placement among available CPUs in event of overheating, which should lead to better performance numbers. See more details on LWN.
  • Tiger Lake enablement – Graphics, thermal & power management, Ethernet
  • Coding-style – Deprecate 80-column warning
