RC522 mod re-wiring documentation

[nflatrea]

Hey @josevcm,

Working my way to mod a RFIO-RC522 module to work as a 13.56MHz antenna just like you did,
are you using TX1,TX2,RX together grounded by VMID ? do you happen to have any re-wiring documentation ?

Hi

The antenna works by removing the rc522 chip and soldering a connector, or wires, between GND and TX1 or TX2; only one of the loops should be sufficient, no other secrets...

I add wiring to README.md as son as I can

Regards
