About this product

The R307 fingerprint module is an advanced optical fingerprint sensor module designed for seamless integration with Arduino and other microcontrollers. This fingerprint optical scanner features a TTL UART interface for direct connection to microcontrollers or PC through MAX232 / USB-Serial adapters. Users can store fingerprint data directly on the module and configure it in 1:1 or 1:N mode for efficient user identification.

Compatibility of Fingerprint R307

The R307 fingerprint module with Arduino is compatible with 3.3V or 5V microcontrollers such as Arduino and NodeMCU. For connecting to a PC serial port, a level converter like MAX232 is required. This makes it versatile for various embedded system applications.
