***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.
