It's quite some time since the last update about my awesome FIDO2 Authenticator project [/category/fido2/]. The project did not stop, no. The latest challenging point was the idea that I should not use the external biometric scanner with UART interface but make a built-in one. So, I have ordered a few more biometric scanner modules and, unfortunately, it took several weeks to deliver.

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.
