Fingerprint Sensor R307 for Arduino and Raspberry Pi

Fingerprint Sensor R307 for Arduino and Raspberry Pi


If you are looking for another way to have user detection/access control added to your project, this module inevitably levels up your system's security. 

This fingerprint sensor uses a high powered DSP chip that does the image rendering,  calculation, searching, and feature found within the memory of this sensor. It can store up to 1000 different fingerprints, and configure it in 1:1 or 1:N mode for identifying the fingerprint. It needs 4.2V to 5v for operating. It consumes 50mA current when working that peaks up to 80mA. 

The module typically has a baud rate of 57600 bps but can be configured through coding. The formula for the baud rate is BR = 960 x N where N = 1 ~ 12.

You can interface this to a microcontroller with the UART pins (RX/TX), and power supply (VCC/GND). This module could interfaces with a USB port by using a USB-to-serial converter like an RS232.
