Revainrating 5 out of 5

Not that broken actually

I used to think all my readers were broken because I couldn't download the firmware from them. It turns out there are multiple versions of the MFRC522.h library, and some of them encourage you to swap the MISO and MOSI pins. Once I did that, they worked great. They work great.

Pros
  • One year trial
Cons
  • Secret
