GROW R307 Optical Fingerprint Sensor UART/USB Embedded Module 44.1×20×23.5mm

GROW R307 Fingerprint Sensor UART/USB Embedded Module 44.1×20×23.5mm The R307 is a compact, self-contained optical fingerprint identification module that integrates an image sensor, on-board processing and flash storage so fingerprint capture, template generation and matching are handled inside the module. On power up the module initializes its sensor and firmware (≈200 ms) and then waits for commands over its serial or USB interface; when a finger is presented the unit acquires a greyscale image and stores it in the image buffer for processing. Enrollment and verification workflows are implemented in the module: the host commands the R307 to capture images, convert them to character files, combine files into templates and store templates in the internal fingerprint library. The module supports both 1:1 verification and 1:N search modes and performs template matching internally, returning match results and scores to the host. Despite its small physical footprint, the R307 exposes a rich instruction set (enroll, search, upload/download image/template, configure parameters, etc.), configurable system parameters (baud, security level, packet length) and a persistent flash library for templates — making it well suited for embedded access control, attendance and biometric projects where the host can be a microcontroller or a PC. Features: Built-in optical sensor plus on-board image processing and template generation. Supports enrollment and matching: 1:1 (verify) and 1:N (search) modes. Internal fingerprint library with persistent flash storage (template storage by PageID). UART (TTL) and USB communication supported; semiduplex asynchronous serial protocol. Configurable system parameters (baud rate factor N, security level, data packet length). Image buffer and two character-file buffers for processing; supports upload/download of images and templates. Hardware RNG available (GetRandomCode instruction).

This is the R307 Optical Fingerprint Reader Sensor Module. 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. The FP module can directly interface with a 3.3 or 5v Microcontroller. A level converter (like MAX232) is required for interfacing with PC serial port.
