MIFARE NFC RFID card reader / writer

RST   D3
SDA   D8
SCK   D5
MISO  D6
MOSI  D7
IRQ   NC
GND   G
3V3   3V3

I am setting this reader up with a Wemos D1 Mini and programming it with esphome. See ~/Documents/source/esphome-projects/esphome/wemos_rfid.

I put the Mini on a proto board and wired up a 12V regulator to make it easy to power in the garage.
