## Description

An all-in-one capacitive fingerprint sensor module with a built-in Cortex processor and commercial-grade fingerprint algorithm. Simply send UART commands to enrol, match, and manage fingerprints — no knowledge of fingerprint algorithms required. The compact rectangle form factor integrates the processor and capacitive sensor in a single chip. Features an embedded human presence sensor that automatically wakes the processor on touch and enters sleep mode when idle, keeping power consumption low. Compatible with hardware platforms like STM32, Raspberry Pi, and Arduino via the onboard UART connector. Key Features Capacitive Touch Sensor – Light touch for fast, reliable verification Cortex Processor – High-performance processing with commercial fingerprint algorithm Simple UART Interface – Command-based control, no fingerprint expertise needed Auto Sleep/Wake – Embedded human sensor for low power consumption All-in-One Design – Processor and sensor integrated in one compact chip Multiple Functions – Fingerprint enrolling, matching, image acquisition, and feature uploading Ideal For Access control and security projects Biometric authentication systems Embedded fingerprint verification applications Raspberry Pi and STM32 projects Package Contents 1× UART Fingerprint Sensor (E) 1× 6-Pin Connection Wire Resources Product Wiki
