Cluster HAT v2.5


Cluster Hat Version 2.5
The Cluster HAT is also available in a Cluster Kit (comes with 4 Raspberry Pi Zero W)

The cluster HAT is physically compatible with the Raspberry Pi Zero 2, but the Zero 2 can consume up to 1.1A, it is not known yet how many Pi Zero 2 can be safely power on using the official 3.0A power supply for the Pi. Please for the moment, use the previous version of Pi Zero and Pi Zero W.


The Cluster HAT interfaces a (Controller) Raspberry Pi A+/B+/2/3/4 with 4 Raspberry Pi Zeros (NOT included). Configured to use USB Gadget mode, it is an ideal tool for teaching, testing or simulating small scale clusters.

USB Gadget Mode: Ethernet and Serial Console.
Onboard 4 port USB 2.0 hub.
Zeros (not included) are powered via Controller Pi GPIO
Individual Raspberry Pi Zero power controlled via Controller Pi GPIO
Connector for Controller Serial Console (FTDI Basic).
Controller Pi can be rebooted without interrupting power to Pi Zeros (network recovers on boot). This feature is not available when using a Pi4 controller.

Short USB rope (colour may vary)

As with most things there are many ways to configure the ClusterHAT. If you know what you’re doing with Linux kernel Gadget mode and networking you can probably skip most of these.

Assembly – Connecting the ClusterHAT (plugging/unplugging the Pi Zeros).
Software – Installing our Customised Raspbian for the Controller and Zeros.
Control – Controlling power to the Pi Zeros
