GROW R503-5V RGB LED DC5V UART Interface MX1.25-6pin Waterproof Capacitive Fingerprint Module Sensor Scanner For Arduino Android


        1. Integrated image collecting and algorithm chip together, ALL-in-One
        2. The flexibility to adapt to the conditions was the fingers, whether it is dry fingers, wet fingers, light texture fingerprints fingers, and old fingers, all have high recognition rate 
        3. The main application areas: can be embedded into a variety of end products, such as: access control, attendance, safety deposit box
1. R503-5V: IP65 Waterproof
2. RGB LED Color, have 7 colors which can be controlled by command.
3. The R503-5V is not compatible with all of GROW's control board.
