Mini Mainboard
The mini mainboard is the smallest form factor openinverter motor control board. It has the same functionality as the regular mainboard but offloads a few components. It is meant to be used as a daughter board on top of an adapter board. The adapter board must (or may) implement:
- The Wifi module socket
- Relay drivers
In addition the mini mainboard allows talking to SPI peripherals. Therefore some pins have double mapping:
- SIG_CRUISE: MOSI
- OUT_BRAKE: MISO
- OUT_ERR: SCK
- OUT_OUVTG: /CS
