Hey guys,
I have bought a RFID writing and reading module. Unfortunately, it is for an Arduino. The following link will show the manual: ... 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

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 ... pberry-pi/
