RFID with a Raspberry Pi Pico

This library enables the MFRC522 module to connect to the Raspberry Pi Pico.

Code mostly from: https://github.com/danjperron/micropython-mfrc522

Wiring

The Raspberry Pi Pico connects to the RC522 module via the SPI interface. The default pinouts are provided below:

RFID Signal Pico Pin
SCK GP2
MOSI GP3
MISO GP4
RST GP0
SDA GP1

Programs and Libraries

There are three programs and 2 libraries:

  • ndef_create.py - creates NDEF tags
  • ndef_erase.py - erases NDEF tags
  • ndef_read.py - reads NDEF tags
  • rfidaccess.py - used for accessing the rfid chip memory
  • mfrc522.py - the main RC522 module library

STL files for 3d printing the case

There are two files: Top.stl and Bottom.stl that you can print out to encase the RC522 module.
