Product Description:

The R307 Fingerprint Module is a biometric device with two interfaces – TTL UART and USB 2.0. The USB 2.0 interface can be connected to a computer, while the TTL UART interface has a default baud rate of 57600 (can be changed) and can be connected to a microcontroller, such as an ARM or DSP, using a serial connection. The module is compatible with 3.3V and 5V microcontrollers, but a level conversion circuit such as MAX232 is required when connecting to a computer.

Features:

Perfect function: independent fingerprint collection, fingerprint registration, fingerprint comparison (1: 1) and fingerprint search (1: N) function.
Small size: small size, no external DSP chip algorithm, has been integrated, easy to install, less fault.
Ultra-low power consumption: low power consumption of the product as a whole, suitable for low-power requirements of the occasion.
Anti-static ability: a strong anti-static ability, anti-static index reached 15KV above.
Application development is simple: developers can provide control instructions, self-fingerprint application product development, without the need for professional knowledge of fingerprinting.
Adjustable security level: suitable for different applications, security levels can be set by the user to adjust.
Finger touch sensing signal output, low effective, sensing circuit standby current is very low, less than 5uA.
