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.
