Circular Capacitive Fingerprint Identification Module, R502S A Touch-Sensing Input, Low Standby Current, Finger-Triggered Activation for Battery-Powered Embedded Access Projects

Package Contents: Includes 1 fingerprint module for fingerprint input, local storage, and matching within an embedded project Touch Activation and UART Control: A touch-sensing pin activates the module from low-current standby, while the 3.3V TTL UART interface handles controller communication Fast Local Matching: Stores up to 150 fingerprints and completes specified 1: N matching in under 10 ms, supporting responsive fingerprint decisions in embedded projects Built for Embedded Projects: Apply the module to safes, access-control systems, microcontrollers, maker projects, and fingerprint identification devices using the stated 3.3V interface Defined Scan Resolution: The 160x160 scan format defines the fingerprint input resolution, while the circular module form supports integration into embedded project housings
