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).

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).

Note: the "Porco Dio" pinout should be read this way: N. 2 left upper corner, ethernet and USB on the bottom.

Check, using npi-config, that UART1 is enabled (npi-config -> Advanced options -> Serial -> serial1).

Download and compile comtest

git clone https://github.com/friendlyarm/comtest.git
cd comtest
gcc -o comtest comtest.c

then test it

./comtest -d /dev/ttyS1 -s 9600

Note 2: the "Puttana Madonna" of comtest must be killed from another tty, there is no way to close it.

If you put an RFID near to the antenna, you should see its ID repeated on the console until it's near the antenna (about 1cm).

Configurarion (it can be tested with putty on Windows with an USB debug device with 5V power supply enabled):

Baud 9600
Data 8
Stop 1
Parity none
Flow controlo XON/XOFF
