  • Prototype and learn cluster applications, parallel computing, and distributed computing concepts
  • Host K8S, K3S, Minecraft, Plex, Owncloud, Nextcloud, Seafile, Minio, Tensorflow
Which Raspberry Pi models are compatible ?
  • CM4 Mini-ITX Cluster supports all Raspberry Pi CM4 with and without eMMC.
Does Raspberry Pi include compute modules ?
  • No, the product only have cluster motherboard and power adapter.
From where CM4 Mini-ITX Cluster boots OS ?
  • You can boot the OS either from eMMC, SD Card or netboot.
Does each node get its own IP address?
  • Yes
How the compute modelues communicate with each other ?
  • The nodes interconnected with the onboard 1 Gbps switch. And, each node has 1Gbps speed.
Do all the slots need to be filled in ?
  • The cluster works with any amount of nodes. You can start with a couple of nodes and scale when needed.
Can I flash compute modules through the board ?
  • Yes, you can flash a compute module using a Micro USB cable.
How do the NIC, Ethernet, USB, HDMI, and audio ports work ?
  • There are 2 USB-A an 2 USB 2.54 Pins on the board.They only connect to CM4 1$. The two HDMI ports are also the same.
  • NIC – There is an 8-port gigabit switch on the board. Each port goes to each node plus one uplink. Two RJ45 out are from the switch. You can use them connect to other network device without extern switch.
Can CM4 Mini-ITX Cluster function from either an ATX power supply 12V ?
  • Yes.
