The Cluster HAT interfaces a (Controller) Raspberry Pi A+/B+/2/3 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).
Kit includes:
- Cluster HAT
- HAT standoffs and screws
- 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.
Jargon buster
Plain-language definitions for the technical terms used above.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
