WAVE-22059 Rectangle-shaped All-in-One Capacitive Fingerprint Sensor (E), Cortex Processor, UART

Rectangle-Shaped All-In-One Capacitive Fingerprint Sensor (E), Cortex Processor, UART Communication

UART Fingerprint Sensor (E)

High performance Cortex processor

Fast Verification, High Stability, Low Power Consumption

Product Features

Based on a high performance Cortex processor, combined with high-security commercial fingerprinting algorithm, the UART Fingerprint Sensor (E) features functionalities like fingerprint enrolling, image acquisition, feature finding, fingerprint matching, and so on. Without any knowledge about the complicate fingerprinting algorithm, all you need to do is just sending some UART commands, to quickly integrate it into fingerprint verification applications which require small size and high precision.

• Easy to use by some simple commands, you don't have to know any fingerprint technology, or the module inter structure
• Commercial fingerprinting algorithm, supports functions like fingerprint enrolling, fingerprint matching, fingerprint image acquisition, and fingerprint feature uploading, stable performance, fast identification
• Capacitive sensitive detection, just touch the collecting window lightly for fast verification
• Highly integrated hardware, processor and sensor in one small chip, suitable for small size applications
• Embedded human sensor, the processor will enter sleep automatically, and wake up when touching, lower power consumption
• Onboard UART connector, easy to connect with hardware platforms like STM32 and Raspberry Pi
