Cannot connect VMA405


#1

Hello there!

I recently got a VMA405 Arduino compatible RFID read and write module. I followed the manual for the module, connected all the wires and installed the necessary libraries, but when i ran the “MFRC522 Test” on the product page nothing happened (and yes, I opened the serial monitor :P). I tried everything, and when i ran the example sketch DumpInfo that came with the MFRC522 library it said that there was a communication failure. Iv’e looked everywhere for a solution, but I can’t find anything.

Here is a picture, I can only put one unfortunately:

It’s hard to see what wire is going where could you post a better picture?
Did you try changing the baud rate on the monitor?

It looks like you have IRQ (Not used) going to AREF
I don’t know if this is the problem but if this is the case try disconnecting it.
