THESE ARE OLD VERSIONS OF CLUSTER HAT. FOR THE LATEST VERSION PLEASE SEE OUR OTHER PRODUCT.

The older versions are fully supported by the official Cluster HAT software images but v1.x do not support controlling hub power or turning all LED off, v1.x will also power off all Pi Zero if the controller is rebooted.

The Cluster HAT (Hardware Attached on Top) interfaces a (Controller) Raspberry Pi A+/B+/2/3/3+ with (up to) 4 Raspberry Pi Zeros (1.1/1.2 or W) configured to use USB Gadget mode is an ideal tool for teaching or testing small scale clusters.

• USB Gadget Mode: Ethernet and Serial Console.
• Onboard 4 port USB 2.0 hub.
• Raspberry Pi Zeros powered via Controller Pi GPIO
• Individual Raspberry Pi Zero power controlled via Controller Pi GPIO (I2C for v2.x and GPIO pins for v1.x).
• Connector for Controller Serial Console (our USB Serial Adaptor or a Sparkfun FTDI Basic).
• V2.x ONLY Controller Pi can be rebooted without interrupting power to Pi Zeros (network recovers on boot) V2.x ONLY on a model earlier than Pi 4.
