Rectangle-shaped All-in-One Capacitive Fingerprint Sensor (E), Cortex Processor, UART

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.
