ClusBerry-2M Industrial IoT controller takes two Raspberry Pi Compute Modules 4

Earlier this year, Techbase introduced the ClusBerry 9500-CM4 cluster system for industrial IoT that can take up to eight Raspberry Pi Compute Modules 4 housed in a DIN rail enclosure.

But for smaller projects and IoT prototyping, the company has now designed ClusBerry-2M, a smaller cluster device including two independent ModBerry I/O mainboards and two Compute Module 4’s that’s equivalent to two ModBerry 500-CM4, but with support for software cluster management tools such as Docker and K3s Lightweight Kubernetes.

The company did not share the full ClusBerry-2M specifications, but we can derive most of the features from the photos, previous products features, and the announcement:

• SoM – 2x Raspberry Pi Compute Module 4 with Broadcom BCM2711 quad-core Cortex-A72 processor @ 1.5 GHz, 1 to 8GB RAM, up to 32GB eMMC flash.
• Storage – 2x M.2 slots for NVMe SSDs
• Video Output – 2x HDMI 2.0 ports
• Connectivity
  • 4x Gigabit Ethernet ports
  • Optional Wi-Fi (IEEE 802.11 b/g/n/ac) & Bluetooth 5.0 module on each RPi CM4 module
  • Optional 5G, 4G/LTE, 3G, or NB-IoT modem plus on-board SIM card socket
  • Optional LoRa or WM-Bus
  • Optional GPS module
  • Optional ZigBee, Z-Wave Ready
  • Optional secondary WiFi & Bluetooth module
• USB – 2x USB 2.0 host ports
• PCIe – 4x mini PCIe sockets for ExCard expansion modules
• I/O expansion ports via 2x 32-pin screw terminals
  • Serial – 4x RS-232 + 4x RS-485 + CAN bus
  • 8x Digital inputs (DI) (0..30V DC)
  • 8x Digital outputs (DO) (0..30V), max. power efficiency: 500 mA
  • 8x Analog inputs – range: 0..10V DC,  18-bit resolution
  • 8x configurable DI/DO (0..30V DC), max. power efficiency: 500 mA
  • 2x 1-Wire
• Misc – RTC, Watchdog timer,  4x monostable switch button
• Power Supply – 2x 9 ~ 30 V DC via 2-pin power header
• Dimensions – 212 x 91 x 61 mm (Casing ABS, DIN rail mounting)
• Weight – 700 to 800g depending on options

From a hardware perspective, I’m not sure what the advantage of getting ClusBerry-2M is over getting two Modberry 500-CM4 gateway since everything is separated including the power source.

The software is the same as for the 8x Raspberry Pi CM4 system with the use of Docker-based and Kubernetes solutions for the detection of new services and traffic, data storage management, automatic deployment and rollback, etc…

The basic version of ClusBerry-2M industrial IoT controller should be available in 2 to 4 weeks, while custom versions will take longer to supply, typically 2 months. The company also mention it will depend on Raspberry Pi Compute Module 4 supplies. There’s no product page specific to ClusBerry-2M at this time, but eventually more details should be found on the ClusBerry page.
