All-in-One (E) capacitive fingerprint reader - 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.

All-in-One capacitive fingerprint reader from Waveshare .

• 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

• 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
