- USB gadget mode: ethernet and serial console.
- Onboard 4 port USB 2.0 hub.
- Zeroes (not included) are powered via controller Pi GPIO
- Individual Raspberry Pi Zero power controlled via controller Pi’s GPIO
- Connector for controller serial console (FTDI Basic).
- Controller Pi can be rebooted without interrupting power to Pi Zeroes (network recovers on boot) (not available when using a Pi 4 controller)
- Cluster HAT
- HAT standoffs and screws
- Short USB rope (colour may vary)
As with most things, there are many ways to configure the Cluster HAT. If you know what you’re doing with Linux kernel gadget mode and networking you can probably skip most of these.
