UART Fingerprint Sensor (E)
From Waveshare Wiki
As a highly integrated capacitive fingerprint recognition module, UART Fingerprint Sensor (E) integrates fingerprint recognition core board and capacitive fingerprint module sensor, which greatly reduces its size. It adopts the high-performance Cortex core, integrates high-security commercial fingerprint algorithm, supports fingerprint enrolling, image acquisition, feature finding, template generating and storing, fingerprint matching, and so on.
- 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.
