Grow R502-a Small Circular Ring RGB LED Fingerprint Module

Product Description

Description 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
The R502-A has circular ring indicator light that can be controlled by command.

***The different between R502-A with R503:
R502-A is thinner and samller, others are same.
If you think R503 is too big, you can chose R502-A.

***The different between R502-A with R502:
We changed the R502's LED to Circular Ring LED.
If you need small and thin module, but need circluar ring LED, you can chose R502-A..
