URU Key – ESP32 FIDO2 Authenticator with Biometrics

I have a small hobby project - FIDO2 Authenticator built on ESP32 chip. For cryptography, I'm using ATECC508A co-processor. I want to use biometric authentication so I connected fingerprint scanner.

So far the device can be used both for user registration and authentication. However, fingerprint recognition is not implemented yet.
