Description
Fingerprint reader module equipped with a 32-bit microcontroller, communicating via simple commands sent via serial interface (RX, TX). The sensor has a memory that allows you to save up to 20 fingerprints and transfer data in the form of photos or a database of patterns to a computer via a USB-UART adapter, microcontroller or otherreader.
- VCC- 5 V supply voltage
- GND- system weight
- RX- serial interface UART receiver - works with 3.3 V
- TX- serial interface UART transmitter - works with 3.3 V
| Pin | Description |
|---|---|
| Pin 1 | TX |
| Pin 2 | RX |
| Pin 3 | Weight - GND |
| Pin 4 | Power supply - VCC 3.3 V - 6 V |
On the first start-up, the fingerprint to be saved in the database should be scanned after sending an appropriate command via the serial interface. Detailed description can be found in thedocumentation.The list of commands can be found in section 3 on page 9.
The module cooperates with microcontrollers equipped with serial interface (RX, TX lines), including Arduino and Raspberry Piminicomputer.
