R308 UART 500DPI Optical Fingerprint access reader

GROW R308 UART 500DPI Optical Fingerprint Sensor Module With 500Finger Capacity

The Grow R308 is a separate fingerprint reader, used high speed special DSP as core parts, compatible different fingerprint sensor. It is an intelligent module which can freely get fingerprint, image processing, verified fingerprint, search and storage, and it can work normally without upper monitor’s participatory management.

• 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 image up to resolution 500 dpi
• A total of eight instruction,Convenient MCU development
• Finger detection signal output
