How many fingerprints can R307 store?

Characteristic file size: 256 bytes. Template size: 512 bytes. Storage capacity: 1000 pieces.

How does R307 work?

R307 fingerprint module is a fingerprint sensor with a TTL UART interface for direct connections to microcontroller UART or to PC through MAX232 / USB-Serial adapter. The user can store the fingerprint data in the module and can configure it in 1:1 or 1: N mode for identifying the person.

What baud rate the serial communication of a fingerprint sensor works?

The first 4 pins are for serial communication with default baudrate of 57600. User may set the baud rate in 9600 -115200 bps. Pins 5 – 8 are for USB communication. Connect the fingerprint reader to the computer via USB-serial converter.

What is fingerprint sensor module?

Fingerprint sensor module is used as a way to verify identity. It is widely applied to computers, mobile phones, electronic door locks, access control systems, security safes, etc.

How does R305 fingerprint module work?

Finger Print Sensor (R305) -TTL UART is a finger print sensor module with TTL UART interface. The user can store the finger print data in the module and can configure it in 1:1 or 1: N mode for identifying the person. The finger print module can directly interface with 3v3 or 5v Microcontroller.
