2. RL78/G1D-SK PMOD module interface
For interface connection, the RL78/G1D-SK PMOD module has 2x6 pin, standard 0.1-inch pitch right angle male
connector. Using this connector, you can program or debug RL78/G1D-SK Bluetooth
®
module. If you program
firmware in Modem configuration, the module can be used for Bluetooth
®
communication
by plugging into one of the
PMOD connectors on the Renesas RDK board like YRDKRL78-G14. The PMOD connector pin number and pin
orientation are shown in Figure 2, and Table 2 shows the pin configuration.

The PMOD connector has flexible interface to communicate either UART or CSI mode. The RL78/G1D-SK PMOD
module can support five communication modes based on programmed firmware as below. Refer document
R01UW0095EJ0117 [2] for detail.
2-Wire UART
3-Wire UART
2-Wire UART with branch
4-Wire CSI
5-Wire CSI
