RFID GPIOS

Tue Jul 17, 2018 10:07 pm

Hey guys,
I have bought a RFID writing and reading module. Unfortunately, it is for an Arduino. The following link will show the manual: http://www.produktinfo.conrad.com/daten ... ND_WRI.PDF.
Now I am trying to find a way to connect the device to my Raspberry Pi 3 Model B V1.2. How do you guys find out which connection on the RFID device belongs to which GPIO on the Raspberry?

Your first port of call has to be https://pinout.xyz/#

Two things to note:
(1) It runs on 3.3v, so it's safe to attach it to a Pi (lots of things run on 5v, so could damage your Pi if precautions aren't taken)
(2) It uses SPI - MISO, MOSI, etc. so should be relatively easy to connect to a Pi

Code: Select all

Arduino®	MAKEVMA405	RPi
+3.3 V		VCC		 1
9		RST		
GND		GND		25
12		MISO		21
11		MOSI		19
13		SCK		23
10		NSS (= SDA)	
		IRQ (not used)

As above,
also that looks like the other RC522 boards (also from your tech doc)

These might help you
