After implementing the Android app for FIDO2 authentication [/2019/08/05/some-progress-with-webauthn/] I started to implement the same functionality on the ESP32 development board.

Recently I've started connecting FPC1020A Fingerprint scanners [/2019/12/03/fpc1020-fingerprint-scanner/] to ESP32 microcontroller and built a working test board for both modifications I have.

The next FIDO2 Authenticator project [/category/fido2/] update is dedicated to the ATECC508A cryptographic chip. I have taken some time and started to write a component library for operating the IC from ESP32 microcontroller.

Autonomous devices like URU Key [/category/fido2] require periodic measurement of the battery voltage. I am going to use very simple schematics and very simple algorithm to understand how much juice my battery has at the moment.
