Renesas RX Family

5.3 Ecosystem

The Ecosystem connectors provide users the option to simultaneously connect several third-party add-on
modules compatible with two popular ecosystems using the following connectors:
1. Two Digilent Pmod™ (SPI and UART) connectors
2. Arduino™ (Uno R3) connectors
5.3.1 Digilent Pmod™ Connectors
Two 12-pin connectors are provided to support Pmod modules where the RX 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 CK-RX65N board also provides jumpers so the 12-pin connector may alternatively be used for 2
independent 6-pin Pmod devices where the top row supports Pmod Type-2 (SPI) and Type-3 (UART) while
the bottom row supports Pmod Type-6 (I
This 12-pin Pmod interface supports +3.3 V devices. Please ensure that any Pmod device installed is
compatible with a +3.3 V supply.
5.3.1.1 Pmod 1 Connector
A 12-pin Pmod connector is provided at J4, Pmod 1.
