Meet DeskPi Super6C – a standard mini-ITX motherboard with up to Six Raspberry Pi CM4 Modules

DeskPi Super6C is a standard mini-ITX board designed to help users with learning cluster applications or distributed Machine learning computing under the vast ecosystem of Linux, cloud-native and Raspberry Pi.

The cluster board which can take up to six Raspberry Pi CM4 modules is now a close competition with the Turing Pi 2 mini-ITX cluster board launched some months ago. They both have the same form factor but the Turing Pi2 can only accommodate up to four Raspberry Pi CM4 modules. The Super6C also has its modules inserted horizontally which gives it a slimmer design than the Turing Pi2.

The board features 2x 1 Gbps RJ45 network interfaces,  3x 12V fan interfaces, 1x on/off switch, 1x reset button, 2x HDMI interfaces for the multiple displays, 2x power supply options for the users and rich PC case front panel headers. Each module on the board has its own peripheral interfaces to help enhance its functions such as a micro USB 2.0 connector, a TF card, an M.2 slot, and a 5V fan interface. The modules also communicate with each other through an onboard 1Gbps switch and each gets its own IP address.

Specifications of the DeskPi Super6C include:

  • SOM Support
    • Has support for up to 6x Raspberry Pi Compute Module 4 (CM4) with or without eMMC
  • Display
    • 1x HDMI 2.0 output
    • 1x HDMI 1.4a (connect to Primary CM4)
  • Network
    • 2x GbE RJ45 LAN ports
    • GbE switch to interconnect all 6x SOMs
  • USB Interface
    • 2x USB-A 2.0
    • 2x Host 2.54 Pins (connect to primary CM4)
    • 6x MicroUSB 2.0 (one for each CM4)
  • Fan
    • 6x 5V FAN header (one for each CM4)
    • 3x 12V FAN header
  • LED / Reset Button
    • 6x LED indicators
    • Onboard ON/OFF and Reset Button
  • Booting Options
    • eMMC, SD card, or the network.
  • Expansion
    • 6x M.2 2280 slots (one for each CM4)
    • 6x TF card slot (one for each CM4)
  • Power
    • 19V to 24V / 100W DC
    • 12V ATX power supply
  • Dimension
    • 170 mm x 170 mm x 21 mm (Mini-ITX)


The DeskPi Super 6C can be used to:

  • handle a MySQL or Postgres database
  • install an Apache server
  • program and manage resources in Linux
  • make and manage your own cloud services
  • script in BASH, Python, and other scripting languages
  • Turn cluster nodes’ resources into one superior server (supercomputer) with the help of simultaneous processing software
  • learning concepts of distributed Machine learning apps

More Details

The board is currently available and sells on three different sites: Seeedstudio and Deskpi online stores sell for $199 while Amazon sells for a much higher price of $249.

More useful details on the cluster board including schematics and setting up instructions can be found on GitHub.
