IIC when changing SW4.1 DIP switch to IIC. This interface may additionally be re-configured in firmware as
several other PMOD types.
This PMOD interface supports +3.3V devices. Please ensure that any PMOD device installed is compatible
with a +3.3V supply.

A 12-pin PMOD Type-2A connector is provided at PMOD 2. The Main MCU can act as the UART/SPI
master, and the connected module acts as an UART/SPI slave device. The Main MCU can be used also as
IIC when changing SW4 to IIC. This interface may additionally be re-configured in firmware as several other
PMOD types.
This PMOD interface supports +3.3V devices. Please ensure that any PMOD device installed is compatible
with a +3.3V supply.
