From Makers Electronics's description

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).

From Micro Ohm's description

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. Integrated image collecting and algorithm chip together, ALL-in-One Fingerprint reader can conduct secondary development, can be embedded into a variety of end products. Users can conduct secondary development, can be embedded into a variety of end products, such as access control, attendance, safety deposit box, car door locks. Low power consumption, low cost, small size, excellent performance, Professional optical technology, precise module manufacturing technics. Good image processing capabilities can successfully capture an image up to resolution 500 dpi Finger detection function.
