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.
  • 5x UART will be available to Compute Module 4 users

Compute Module & Industrial IoT symbiosis

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?

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.

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+
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:

  • 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,
  • Current flash memory (eMMC) options: 8GB / 16GB / 32GB from CM3+ will probably stay the same,
  • H.265 (4kp60 decode), H264 (1080p60 decode, 1080p30 encode) might replace outdated H.264 (1080p30)
  • 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.

To ensure constant development of TECHBASE’s solutions and cutting-edge technology, the NanoPi platform part of ModBerry series is expanded by updated ModBerry M300 N2 product, based on NanoPi NEO2. The new addition features Quad-core Cortex-A53, twice more RAM than previous version of NanoPi NEO and Gigabit Ethernet for fast communication.

For even wider range of communication interfaces and application possibilities, TECHBASE offers now ModBerry M300 N2+ based on the NanoPi NEO Plus2. M300 N2+ is equipped with 8GB eMMC, features more USB ports, Gigabit Ethernet port like M300 N2 and is supported with onboard Wi-Fi/Blutetooth 4.0 to ensure many channels of data management.

ModBerry M300 series can optionally support an external 2.5″ SATA hard disk and 2242 SSD storage units with M.2 interface thanks to onboard JMS567 USB to SATA controller. With extra storage space, data management of specific installations would be more convenient than sending all unprocessed data into cloud or directly to user.

OrangePi capabilities

To meet the Industrial IoT market demands the ModBerry family joined new embedded computer platform, offering adjustable solutions for every industrial installation. ModBerry M300 O1/O2 series is formed by two OrangePi module boards offering different approach to IoT than NanoPi solutions.

ModBerry M300 O1 based on OrangePi Zero Plus features Allwinner H5 (Quad-core Cortex-A53) SoC, moderate 512MB RAM, storage memory option with microSD slot, USB and Gigabit Ethernet port. The wireless communication is supported with onboard Wi-Fi module.

Offering much higher performance and wider feature range, the ModBerry M300 O2 features same SoC as M300 series, but thanks to OrangePi Zero Plus2 means, the device is equipped with onboard 8GB eMMC, extra microSD expansion slot as alternative and wired/wireless interfaces, e.g. HDMI, Wi-Fi, Bluetooth 4.0.

ExCard modules to peak the performance

Every TECHBASE’s industrial computer is supported by ExCard add-on modules for extra RS-232/485 serial ports, Ethernet ports, PCIe slots, analog input and output, digital I/Os, relays, M-Bus interface, opto-isolation, accelerometer, etc. To provide specific communication paths, ModBerry can be rigged with additional Wi-Fi/Bluetooth module, 3G/LTE, NarrowBand-IoT, LoRa, ZigBee, GPS and Wireless M-Bus.

The latest options for ModBerry series are:

  • SuperCap expansion, to provide constant power supply as a UPS option
  • OLED 0.96” & new OLED 1,3″ screen, allowing the control without the need of connecting into the device
  • ESP32 module as a security chip, to add a firewall into control installation and ensure constant operation of the device, even with power drops and random events
  • Aluminum case, to grant much higher durability for extra harsh industrial conditions
  • Mentioned earlier SATA/M.2 SSD controller for extra data storage

The updated M300 availability

Currently all the updated M300 samples, including M300 N2, N2+, O1, O2 are available on demand. Please contact TECHBASE’s sales department via https://iot-industrial-devices.com/ contact form with specific requirements to receive an offer that will suit the project’s needs. Since the M300 update is still under the development, specific datasheets will be available in mid-February. The pricing of each unit may vary on the basis of configuration and order quota.

The latest configuration of ModBerry 500 device presents the important milestone in TECHBASE’s offer. The introduction of two platform symbiosis, RaspberryPi Compute Module 3 assisted with Espressif’s ESP32 module brings new possibilities of application to life. High performance of CM3, if compromised by exposition to harsh environmental conditions or sudden drop of power, is aided with low-powered ESP32’s real-time system to continue operation of the device. ESP32 module can be battery powered, same as standalone Moduino series, based on similar solution.

ESP32 subsystem for ModBerry 500

Main difference between ESP32-aided ModBerry device and ESP32-based Moduino is that the first one benefits from low-power module aid to prevent errors and downtimes. ESP32 compared to Compute Module 3 works much longer on battery power supply and offers extended sleep modes. Real-time system of ESP32 and simplified communication between ESP32-aided ModBerry device and Moduino controllers drastically shortens the time needed for the system implementation and the cost of maintaining the application. It also enables the use of Espressif’s Wi-Fi-based technology in the ESP-NOW and ESP-MESH networks.

The separate ModBerry-Moduino Ecosystem, working as a separate devices is a solution for scattered object and installations monitoring – with the use of wireless communication interfaces (e.g. LoRa, NarrowBand-IoT, ZigBee, Wi-Fi, Bluetooth, etc.), rather than standard wired networks. For more information ask TECHBASE via one of contact form at: https://iot-industrial-devices.com/ & http://moduino.techbase.eu/

Coming soon

TECHBASE plans further development of the product, particularly the issue of remote access to input/output resources and use of ESP32 as a Security Chip – hardware layer protection against hacking (very important issue in current IoT business).

 

Introduced with Moduino series, TECHBASE developed further the project of modular aluminum case for their devices. The latest version of housing allows ModBerry to expand in any dimension, supporting additional extension cards (e.g. I/Os, modems, opto-isolation, accelerometer, etc.) and DIN rail mount, that can be retracted into device itself. TECHBASE constantly improves the project to support different platforms (e.g. Raspberry Pi Compute Module 3, NanoPi, ESP32, UpBoard and probably more in the nearest future) and brings them to Industrial IoT world.

Supercapacitor power support for ModBerry

To improve the possibilities of ModBerry devices, TECHBASE added supercapacitor UPS option for ModBerry 500 configurations. Additional power supply available at emergency situations, such as power drop or loss, allows the device to log the recently acquired data and send the notifications to user regarding the occurred event. The supercap support for ModBerry ensures safe system shutdown and protects memory from fragmenting, so there is no need to use diagnostic tools afterwards.

ModBerry enhanced with OLED screen

Just like ESP32-based Moduino series, the ModBerry computers can be now equipped with OLED 0.96″ 128×64 screen via i2c extension protocol. The is small, only about 1″ diameter, but very readable due to the high contrast of an OLED display. Because the display makes its own light, no backlight is required, therefore reduces the power required to run the OLED.

Moduino based on ESP32 can now be equipped with TECHBASE’s original mBus10/60/400 converter module. The converter operates as a M-Bus Master and allows user to connect up to 400 standard M-Bus receivers (Slaves) through M-Bus Master output or fewer devices at a higher M-Bus load over long distances. Moduino, as a fully capable Industrial IoT device, can now be used with every device equipped with M-Bus interface, e.g. heat meters, electricity meters, gas meters, executive modules, recorders, measuring instruments.

Wireless M-Bus support

TECHBASE has added high performance module for wireless M-Bus connectivity and multi-hop networking into Moduino series expansion options. The module is configured as an embedded micro system or simple data modem for low power applications in the metering specifically allocated band of 169 MHz or in the ISM band of 868 MHz. The device is can be configured for interoperability in a WMBus network for Industrial IoT applications.

The RF implementation guarantees best-in-class performance in terms of covered area and power consumption. The output power can be increased up to +30 dBm on the 169 MHz band (+27 dBm on optimized version for highest power efficiency) and up to +15 dBm on the 868 MHz band. The extremely reduced power consumption gives access to long lasting battery life requirement (up to 2 μA in sleep mode for wireless M-Bus module with an RTC clock running).

The Moduino devices  can be provided with a W-MBus stack specifically developed by Embit for the platform that allows to integrate the module in the desired system without effort and simplify the interaction in WMBus networks.
