FINGER

SKU:U008

Description

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)

Product Features

  • 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
