RGB led lighting module


I’ve started a new project: a RGB led lighting module, that can be controlled from a central communication node.

I’ll be using some SMD rgb leds, in 5050 case, that i ¬†got from e-bay.

The Imax is specified to 40mA, but i’ll be running them at 30mA max, to keep the heat down.

The design features are :

  • 50x50mm per module
  • cheap controller, JTAG interface, enough cpu power for high resolution/ speed PWM
  • the ability to run stand-alone, following a pre-programmed sequence
  • RS485 line drivers
  • wide input voltage range
