Support of different versions of PN532 NFC/RFID

ESPHome
1

I am wondering if this PN532 NFC/RFID https://nl.aliexpress.com/item/PN532-NFC-RFID-module-User-Kits-Arduino-compatible/1450298695.html is supported by ESPHome because another one is dispayed at the docs here https://esphome.io/components/binary_sensor/pn532.html ?

Does anyone have tried it yet?

Well if you have a look at details of article you linked on Ali, it looks to be based on correct chip and have the needed pins to link it at ESP as indicated in ESPHome documentation for it, so I would say it looks to be fine ! Best way is to buy one and try it :wink: You can find also on the board the two switches as stated in ESPHome documentation !
Please report here your results so it can help other people :slight_smile:

I bought the same kit. But i’m having trouble to identify the correct pin on the board to connect to IO in the ESP32. Can you show your connections?

Thanks

I am using this configuration (ESPHome YAML) with a Wemos D1 Mini.

  clk_pin: D0
  miso_pin: D1
