Overview

Introduction

As a highly integrated capacitive fingerprint recognition module, UART Fingerprint Sensor (E) integrates fingerprint recognition core board and capacitive fingerprint module sensor, which greatly reduces its size. It adopts the high-performance Cortex core, integrates high-security commercial fingerprint algorithm, supports fingerprint enrolling, image acquisition, feature finding, template generating and storing, fingerprint matching, and so on.

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, supports functions like fingerprint enrolling, fingerprint matching, fingerprint image acquisition, and fingerprint feature uploading, stable performance, fast identification.
• Capacitive sensitive detection, just touch the collecting window lightly for fast verification.
• Highly integrated hardware, processor and sensor in one small chip, suitable for small size applications.
• 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.

Interface Description

• VIN:3.3V
• GND:Ground
• RX:Serial data input (TTL level)
• TX:Serial port data output (TTL level)
• RST:Sleep Control Interface:
  • High level: module power supply - start
  • Low level: module power down - sleep
• WAKE: wake-up pin, when RST is at low level (sleep), the fingerprint module will be activated when the finger touches the surface of the collector, and this pin outputs a high level.
