Remote access to Raspberry Pi Compute Module 4 platform for Software Developers

Low Raspberry Pi availability on the IoT market

Many companies have been impacted by the global chip shortage and supply chain issues, including electronics and automotive industries. This problem also touched the main producer of small board computers, Raspberry Pi. Company’s CEO, Eben Upton said that they had difficulty meeting demand for many of its products, but that it was taking steps to ensure devices were delivered despite supply constraints. 

“We’ve consistently been able to build around half a million of our single-board computers and Compute Module products each month. Where units do appear, bots often attempt to scalp stock which is then resold at higher prices elsewhere” said Upton. 

Sadly, for the average consumer who wants to build home projects or test software with Pi products, Raspberry Pi is prioritizing commercial and industrial customers.

With the help of the integrated ESP32 module and the Arduino environment, the module can manage boot, sleep mode, or safe shutdown of the device in case of unexpected drop in the power network.

In the last few years developers marketed a wide range of ARM-based development boards, lacking in enhanced power management, especially sleep and wake up modes, commonly used in PC-grade computing. These boards are not adjusted for battery power supply, so it’s natural that sleep/wake functions should be implemented. In connection with the development of solutions based on Linux-SBC, key factor is adding sleep modes to any remote installation

ESP32 based addon module for Raspberry Pi

The TECHBASE sleep/wake add-on module can wake a device using a scheduler/timer that has built-in algorithms or can be programmed by the user. Modules based on ESP32-ROVER are used in Moduino X series boards. For Raspberry Pi, the ESP32 provides a lightweight and low-power solution. The program can also be woken up by external triggers, such as changes in input state. Various scenarios can be configured for sleep, shutdown, and wake functions, ensuring continuous operation of devices, the security of data, and the continuity of work in the event of a power outage.

Advanced power management solution

Most advanced configuration includes use of ESP32 module, known from the successful, lightweight Moduino X series, for extra logic for wake up / sleep scripts. This addon will allow the RaspberryPi-based ModBerry device to be woken up by the internal ESP32 controller

Moduino-ModBerry symbiosis allows a wide range of wake-up/sleep schedule customization, in order to perform best and save energy according to power supply state. Arduino and MicroPython environments provide libraries to control different scenarios of data and power management.

Sleep mode with additional power backup

Industrial Raspberry Pi with LoRa support is a must

As the remote application market is growing rapidly, technology also needs to progress, ensuring greater range and transmission speed while reducing energy consumption. Technological progress makes it possible to create innovative standards for new, sophisticated applications that facilitate our life and work. One of wireless connection choices can be LoRa technogoly.

What exactly is LoRaWAN?

LoRa (Long Range Radio) technology with low data throughput allows IoT and M2M applications to communicate wirelessly over 15 kilometers, with a battery life of more than 10 years. LoRa allows you to connect millions of wireless nodes with compatible gateways and has several key advantages over other wireless solutions. For example, it uses spectrum spreading modulation with the ability to demodulate a signal 20 dB below the noise level.

LoRa uses license-free sub-gigahertz radio frequency bands like 433 MHz, 868 MHz (Europe) and 915 MHz (Australia and North America). LoRa enables long-range transmissions (more than 10 km in rural areas) with low power consumption.[4] The technology is presented in two parts: LoRa, the physical layer and LoRaWAN (Long Range Wide Area Network), the upper layers.

Source: https://en.wikipedia.org/wiki/LoRa

Compared to 3G and 4G cellular networks, LoRa technology is also better scalable and more cost-effective for embedded applications. It has a much greater range than other popular wireless protocols, which allows devices to operate without amplifiers, reducing the total cost of the application.

Thanks to scalability, reliable communication, mobility and ability to work in difficult external conditions, the LoRa module is perfectly suited for use in a wide range of wireless monitoring and control applications that do not require high transmission speeds. Examples of applications may include smart city (street lighting sensors, motion sensors), energy (intelligent measurement of electricity / water / gas consumption) and industrial / commercial / home applications, among others HVAC, intelligent devices, security systems and lighting.

LoRa Coverage

Use of LoRa 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. With the spread of internet access, the possibility of using wireless connectivity for a new type of service and application has opened. Terminology such as M2M (Machine to Machine) – remote communication between devices and IoT – a network of applications and devices communicating with the Internet have been created.

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 LoRa Gateway from TECHBASE.

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.

Available open source ventilator projects to help COVID-19 patients

When the news came out that ventilator shortages could be a problem, many saw the need for alternatives to the big manufacturers and rushed to create them. Unlike industrial projects, these projects were open and shared. Currently, Robert Reed and his group are starting to systematically evaluate the ranking of over 80 such open source projects.

Their work is a milestone in public research and development efforts to solve problems. For many ventilator builders, the group recognized the need for independent evaluation and testing of various projects. This control provides important feedback to both designers and future builders. This is a service you can expect from government regulators if they can act very quickly.

Reid and colleagues Geoff Mulligan, Lauria Clarke, Juan E. Villacres Perez and Avinash Baskaran to help to learn about these studies. This includes submission of modular team designs that allow distributed production and unique suggestions for testing and monitoring these systems. This is called VentMon.

Industrial Arduino-like devices as a base of medical equipment?

When industrial IoT devices and edge devices, like medical equipment work together, digital information becomes more powerful. Especially in contexts where you need to collect data in a traditional edge context, or control the servo-motors of a ventilatr. You can then remotely monitor the container using the sensor.

By introducing AI (artificial intelligence) into the device itself, edge computing can also make more context-sensitive, quick decisions at the edge. Data gathered from the sensors can be transferred to the cloud at any time after local work has been completed, contributing to a more global AI process, or archived. With the combination of industrial IoT devices and advanced technology, high quality analysis and small footprint will become the AI standard in 2020.
