Cluster HAT v2.5

The Cluster HAT v2.5 interfaces a Raspberry Pi 4 (or older A+/B+/2/3) with 4 Raspberry Pi Zero W boards (not compatible with the Raspberry Pi Zero 2 W due to the additional power the Zero 2 requires).

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
• Raspberry Pi Zeros are powered via Controller Pi GPIO
• Individual Raspberry Pi Zero power controlled via Controller Pi GPIO
• Connector for USB Serial Adaptor (FTDI 3.3v)
  
• Controller Pi can be rebooted without interrupting power to Raspberry Pi Zeros (network recovers on boot)
• New! Pads for adding a 5V fan

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
