Product description: Fingerprint reader - with STM32F205 32-bit
Fingerprint reader module equipped with a 32-bit STM32F205 microcontroller, communicating via simple commands sent via UART (RX, TX) serial interface. The sensor has a memory that allows you to save up to 1000 fingerprints and transfer data in the form of photos or a database of patterns to a computer via a USB-UART adapter , microcontroller or other reader.
The module cooperates with microcontrollers equipped with serial interface (RX, TX lines), including Arduino and Raspberry Pi mini computer .
