RFID Sensor NXP MFRC522


Introduction

This embedded sensor, that provides a RFID sensor at 13.56 MHz, is based on the NXP MFRC522 chipset and it is compatible with the SPI serial interface. For ease we are going to connect it to the FTDI FT232H device, of which there is a dedicated page on this site - refer to the above page for installation.

 

Connection via SPI

This sensor must be connected to the FTDI FT232H development board via SPI protocol. The connection connectors are listed below:
