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
- 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
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.
