“I can't make it work with my RPi pico, yet, but I am confident that it's a lack of user proficiency I can make the pico recognise it's connected to an i2c device but I can't manage to detect any rfid tags. Will try again when I have more time... it seems like a good challenge, but not for beginners. I think there's easier kits to use for reading rfid tags if you need it for a practical purpose.”
