AS608 Optical Fingerprint Recognition Module STM32 51 Single Chip Microcomputer Fingerprint Collection Module

Attendance and access control development/fingerprint collection/STM32 51 microcontroller

The AS608 module adopts the AS608 fingerprint identification chip from the famous domestic fingerprint identification chip company Hanzhou Shengyuan Chip Technology Co., Ltd. The chip has a built-in DSP computing unit and inherits the fingerprint recognition algorithm, which can efficiently and quickly collect images and identify fingerprint features. The module uses USB or UART interface to communicate, users do not need to repeatedly study the complicated image processing and fingerprint identification algorithm, only need to control the module through a simple serial port and USB according to the communication protocol. This module can be applied to various attendance machines, safes, fingerprint access control systems and other occasions.

Instructions for use:

The 5 pins and 6 pins of the module can be selectively connected, and can be left unconnected when not in use.

Pin 1 (red wire): the main power supply of the module, connected to 3.3v power supply (do not connect to a power supply above 3.3V, otherwise the module will be burnt)

2 feet (yellow wire): module serial port T× (transmitting end), connected to MCU or TTL serial port RX (receiving end)

3 feet (white wire): module serial port RX (receiving end), connected to MCU or TX (transmitting end) of TTL serial port

4 feet (black wire): module power ground, connect to 3.3V power ground (negative)

Pin 5 (blue line): module touch sensor signal output (high level means touch is detected), VTI must be connected to 3.3v

Pin 6 (green wire): module touch sensing circuit power supply (3.3v), can be connected with pin 1 (red wire) in parallel
