High-quality PCB FR4 Grade with FPT Certified

as the coil trigger voltage is 5V

The threshold value of the sensor module can be set by varying the onboard potentiometer

The main function of carbon film resistors is to reduce the current flow in a circuit

GT-521F32 Finger Print Sensor Module SMPS High-quality PCB FR4 Grade withThe GT521F32 Fingerprint Sensor Module is made to be compatible for hobbyists projects and rapid prototyping. It is a small embedded module that consists of an optical sensor mounted on a small circuit board. The optical sensor scans the fingerprint, and these scans are processed by an onboard 32 bit microcontroller. You can also check out the GT511C3 Fingerprint sensor for a cheaper alternative. This module is the low cost version of the GT 521F52
