Pin 2 on the Arduino schematic is really GPIO2 on the NINA, therefore it should not be labeled GPIO34. This is confirmed by the fact that the pin numbering on the Arduino schematic matches the pin ...

Previously we interfaced MFRC522 RFID Module and EM-18 RFID Reader with Arduino. In this tutorial, we are going to interface RDM6300 RFID Reader Module with Arduino Nano. The RDM6300 RFID Reader is ...
