Raspberry Pi Compute Module pin definitions.
This pin provider should be used for Raspberry Pi models:
- RaspberryPi CM
- RaspberryPi CM3
- RaspberryPi CM3 Lite
- RaspberryPi CM3+
NOTE: Unlike the older models, the Raspberry Pi CM4 only exposes 28 GPIO pins which correspond to the
GPIO pins on the Raspberry Pi 4. Thus for the CM4 you should not use the RCMPin pin provider,
but rather use the traditional 'RaspiPin' pin provider just like you would for a RPi 4B.
