FINGER Unit is a fingerprint sensor based on the FPC1020A chipset.
This all-in-one fingerprint sensor makes fingerprint adding, verification and managing super simple.
Operated by the UART protocol, Compact size and ultra-low power consumption makes it very attractive to use around M5Stack series product. it performs fast fingerprint matching with highest security level and optimal user convenience. You can program to set the fingerprint recognition comparison level and different security level . if you ever consider secure your project with biometrics, don't forget to include this M5unit FINGER.
This unit communicate with M5Core by UART protocol connected via PORTC
UART settings:
Baudrate(default: 19200bps)
Start bits(1 bit)
Stop bits(1 bit)
Parity(no)
Use capacitive area array semiconductor fingerprint sensor
Each pixel of the sensor has a pixel quality of 256 gray levels
1: N recognition and 1: 1 verification function
Support finger 360 rotation recognition
Fingerprint comparison and search function
Fingerprint Attendance Machine
Fingerprint Locker
