Product Description
AS608 is a fingerprint scanner and reader module but does more than that like fingerprint enrollment, image processing, print matching and many more. It processes the data and sends processed data to the microcontroller through serial. The device uses a DSP chip that does image rendering, feature finding, calculation and searching. It has an in-built flash memory that stores the data of fingerprint and enrolls new – up to 162 fingerprints can be stored. It interfaces with the controller or any other system with TTL serial and sends packets of data to take photos, detects print, hash, and search. The device has a red and green LED light indication for the wrong and right prints.
The module can be easily tested with a window software as well as user can enroll using the software and can see the image of the fingerprint on the computer.

The R307S Optical Fingerprint Reader Sensor Module.
R307S 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.
