5.3.2 SparkFun Qwiic Connector
®
A SparkFun Qwiic connector is provided at J30. The main MCU acts as a two-wire serial master, and a
connected module acts as a two-wire serial slave (data lines are shared with Grove 1 and Grove 2).

5.3.3 Digilent Pmod™ Connectors
Two 12-pin connectors are provided to support Pmod modules where the RA MCU acts as the master, and
the connected module acts as a slave device.
These interfaces may be configured in firmware to support several Pmod types such as Type-2A (expanded
SPI) and Type-3A (expanded UART).
The EK-RA4E2 board also provides jumpers so the 12-pin connector may alternatively be used for Pmod
2
Type-6A (I C).
The default 12-pin Pmod interface supports +3.3 V devices. Please ensure that any Pmod device installed is
compatible with a +3.3 V supply.
The Pmod interface option for Type-6A (I
capable modules are used when this option is selected.
5.3.3.1 Pmod 1
A 12-pin Pmod connector is provided at J26, Pmod 1.
