Makerfactory M5Stack fingerprint sensor

The fingerprint sensor from the M5Stack series is an all-in-one fingerprint sensor that makes it easy to add, verify, and manage fingerprints. The UART protocol, compact size, and extremely low power consumption make it very attractive to use. It performs a fast matching of fingerprints with the highest level of security and optimal user comfort. You can program the matching level for fingerprint recognition and set a different security level. If you ever consider securing your project with biometric data, don't forget to include this M5 unit. This device communicates with the M5-Core via the UART protocol, which is connected through PORTC. UART settings: Baud rate (default: 19200 bps), Start bits (1 bit), Stop bits (1 bit), Parity (none).
