#19557 Hi all,

is it possible to connect the mfrc522 to a esp8266?
My idea is to realize a RFID access control that will send user access information to a NODERED flow on a Raspberry PI. In this case the ESP8266 will get the card info from the RFID reader and use it as payload to be sent to Nodered server.
I think SPI is an option but I would like your help to start in the right direction. :D
Thanks

#20247 Hi,

I got esp8266 working with RC522 using the Arduino enviroment to programm esp8266 and RC522 Library for Arduino connecting RC522 via SPI to esp8266.

If more information needed please let me know - I'm glad to share my working setup with you....

#20261 I really love to see this too.
For my next small project I need exactly that.
hooking up this inexpensive RFID reader (MFRC522 modules) to ESP8266.
The read card id is sent to a server.
So should be really simple to built up.
Is there already a port of this module yet?
