The standard ClusterHAT package contains:
- 1x ClusterHAT PCB*
- 4x 12mm M2.5 standoff
- 8x 6mm M2.5 screw
- 4x stick on foot
- USB Cable*
(* PCB/LED/USB Cable colour may vary)
- 1x Controller Raspberry Pi (A+/B+/B2/B3)
- 1-4x Raspberry Pi Zero (1.2/1.3/W)
- 2-5x Micro SD memory card
- Pi Power Supply (2-2.5A capable)
- Network Cable / WiFi dongle / etc.
(* PCB/LED/USB Cable colour may vary)
The ClusterHAT will work with most models of Raspberry Pi (as above) but please be aware the Raspberry Pi 3 may reduce the CPU speed when hot which may happen with high CPU usage with or without a HAT. A 20cm (or longer) USB cable (Type A plug to Micro-B plug) is required to connect the ClusterHAT to the Controller Pi USB port. The Controller and each Zero requires a Micro SD card (8GB or bigger recommended). A power supply capable of supplying 2 Amps is recommended (2.5A when using a Pi 3).
Disconnect the Pi from all sources of power (USB Power/HDMI/USB Peripherals/etc.) before connecting the ClusterHAT.
- Attach the 4x standoffs to the Controller Raspberry Pi with the supplied screws
- Place the ClusterHAT on top of the Controller Pi
- Secure the ClusterHAT to the Controller Pi using 4 screws
- Connect the USB cable between Controller Pi and ClusterHAT
- Plug 1-4 Raspberry Pi Zero into the ClusterHAT
Care must be taken when connecting/disconnecting Pi Zero from the ClusterHAT as excessive force may damage the ClusterHAT connectors and/or Pi Zero.
To remove the Pi Zero we advise securely holding the Controller/ClusterHAT with one hand and then using the thumb and index finger of the other hand to gently pull the Pi Zero from the socket.
