I'm trying to wire the mfrc522 and the huzzah but i can't seem to figure out the rst pin.
use Wemos table from your link. here is the mapping to esp8266 io pins
RST/Reset D3 = io 0 SPI SS D8 = io 15 SPI MOSI D7 = io 13 SPI MISO D6 = io 12 SPI SCK D5 = io 14
If you want, you can use any pin for SS and reset. See the examples.
#define SS_PIN 4 #define RST_PIN 5 MFRC522 mfrc522(SS_PIN, RST_PIN);
