Renesas RA Family
Note: Exercise caution while modifying power source trace jumpers, E1 and E2. Permanent damage
to the FPB-RA4E1 board and/or connected modules may result.
5.3.1.2 Pmod 2
A 12-pin right angle connector can be fitted at PMOD2. A suitable part is Samtec SSW-106-02-T-D-RA. 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.
