Mini Mainboard

Mini mainboard front

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
