Product description: Fingerprint reader - TTL GT-511C3 - 200 prints memory
A module with a fingerprint reader equipped with a 32-bit microcontroller, communicating by means of simple commands sent through a serial interface (RX, TX). The sensor has a memory that allows you to save up to 200 fingerprints and transfer data in the form of photos or a database of patterns to a computer via USB-UART adapter, microcontroller or otherreader.
Side hooks with holes of 2.5 mm in diameter facilitate mounting of the module. TheJST- SHconnector is used to connect signals.The system has four outputs:
- 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
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.
