Hi there!
I was looking at this RFID module for an upcoming project, and I was wondering can it be used with arduino/esp32 as well, and is there a library that can help with this?

Hi Kaylee,
Yeah, the onboard IC has an arduino library here: MFRC522-spi-i2c-uart-async - Arduino Reference (I havent tested this so cant 100% confirm) - though it definitely does work with micropython on the ESP32 (google and chatGPT are you friends 
)

Hi Kaylee,
I’ve had some luck in the past getting a Piicodev magnetometer working on an Arduino with some library I found on GitHub. It wasn’t the easiest process however.
As Liam stated the ESP32 also uses MicroPython and the provided libraries with work there.

There’s some fantastic hacking going on in this thread where a user is extending the range with a custom antenna
