Waveshare UART all-in-one capacitive fingerprint sensor in rectangle shape (E), Cortex processor

Functionality
Based on high-performance cortex processor, combined with high-security commercial fingerprint algorithm, UART fingerprint sensor (E) has functions such as fingerprint enrollment, image acquisition, feature search, fingerprint matching and so on. Without any knowledge of complicated fingerprint algorithm, all you need to do is just send some UART commands, quickly integrate it into fingerprint verification applications that require small size and high precision.
1. Easy to use with some simple commands, no need to know any fingerprint technology or inter-module structure
2. Commercial fingerprint algorithm, support functions such as fingerprint enrollment, fingerprint matching, fingerprint image acquisition and fingerprint feature uploading, stable performance, fast identification
3. Sensitive capacitive sensing, lightly touch the collection window for quick verification
4. Highly integrated hardware, processor and sensor in a small chip, suitable for small size applications
5. Built-in human sensor, the processor will automatically enter sleep and wake up when you touch, lower power consumption
6. Onboard UART connector, easy to connect with hardware platforms such as STM32 and Raspberry Pi
