5.3.1.2 Pmod 2
A 12-pin Pmod type-2A connector is provided at connector PMOD2. The RA MCU acts as the SPI master,
and the connected module acts as an SPI slave device. This interface may additionally be re-configured in
firmware as several other Pmod types.
This Pmod interface supports +3.3 V devices. Please ensure that any Pmod device installed is compatible
with a +3.3 V supply.
