RDM6300

Pins and voltage

RDM6300 can be powered from NanoPI +5V pin. However, it does not require voltage adapters for signals, as the signals are 3.3V (in and out).

Test

You can connect pins 4 (VCC 5V), 6 (GND), 8 (UART1 TX) and 10 (UART1 RX) to the corresponding pins in the board (of course, TX to RX and vice versa).
