Product description: Capacitive fingerprint reader All-in-One (E) - with ARM Cortex - UART - rectangular - Waveshare 22059
Integrated, capacitive fingerprint reader from Waveshare . It was equipped with a UART interface . The reader is based on a high-performance Cortex processor with high-security commercial fingerprint algorithms, and supports fingerprint enrollment, image acquisition, feature search, template generation and storage, fingerprint matching and much more.
The main features of the fingerprint reader module
- Also suitable for beginners - easy to use with a few simple commands, no knowledge of fingerprint technology or the internal structure of the module required
- Commercial fingerprint algorithm, stable performance, fast identification
- Very sensitive detection, it is enough to lightly touch the identifying area (without pressing) to trigger the reader
- Highly integrated hardware, processor and sensor in one small chip, suitable primarily for small size applications
- Allows you to freely input / output fingerprint images, fingerprint function files and other fingerprint related activities
- Equipped with a built-in UART connector, easy to connect to hardware platforms such as STM32 and Raspberry Pi
Pinout description
- VIN - power pin 3.3 V
- GND - the ground of the system
- RX - serial data input (TTL level)
- TX - serial data output (TTL level)
- RST - RESET pin, sleep control interface:
- high level: module power supply - start
- low level: module shutdown - sleep
- WAKE - wake up pin, when the RST pin is in the low state (sleep), the module will be activated, when the finger touches the collector surface, it will go high
