Overview

This is a highly integrated round-shaped all-in-one capacitive fingerprint sensor module, which is nearly as small as a nail plate. The module is controlled via UART commands, fairly easy to use. It's advantages includes 360° omni-directional verification, fast verification, high stability, and low power consumption, etc.

Based on a high performance Cortex processor, combined with high-security commercial fingerprinting algorithm, the UART Fingerprint Sensor (C) features functionalities like fingerprint enrolling, image acquisition, feature finding, template generating and storing, fingerprint matching, and so on. Without any knowledge about the complicate fingerprinting algorithm, all you need to do is just sending some UART commands, to quickly integrate it into fingerprint verification applications which require small size and high precision.

Features

  • Easy to use by some simple commands, you don't have to know any fingerprint technology, or the module inter structure
  • Commercial fingerprinting algorithm, stable performance, fast verification, supports fingerprint enrolling, fingerprint matching, collect fingerprint image, and upload fingerprint feature, etc.
  • Capacitive sensitive detection, just touch the collecting window lightly for fast verification
  • Hardware highly integrated, processor and sensor in one small chip, suit for small size applications
  • Narrow stainless steel rim, large touching area, supports 360° omni-directional verification
  • Embedded human sensor, the processor will enter sleep automatically, and wake up when touching, lower power consumption
  • Onboard UART connector, easy to connect with hardware platforms like STM32 and Raspberry Pi
