GM861S Fingerprint Sensor 3.3V 70mA Module

GM861S Fingerprint Sensor 3.3V 70mA Module

The GM861S Fingerprint Sensor Module provides fast and reliable fingerprint enrollment, storage, and verification for electronic security applications. Operating from a 3.3V supply with low power consumption, it is well suited for battery-powered and embedded devices. The module communicates through a UART interface, allowing easy integration with microcontrollers such as STM32, ESP32, Arduino (using level shifting if required), and Raspberry Pi.

Its compact design and high recognition accuracy make it an excellent choice for smart locks, access control terminals, safes, attendance systems, and IoT security products. The module performs fingerprint matching internally, reducing the processing load on the host controller while providing quick and secure authentication.
