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.
