RGB controller

 

Hi! I like decoration lights, so RGB controllers are "must have" devices for me =)

I decided to make module system, so for any light power I need only different type of repeaters instead of making new controller board for each purpose.

So this is main RGB controller board designed for my KSN20 CAN network:

Controller is based on STM32F042F6 MCU (I love 042 series due to small case available and integrated CAN peripheral).

Depend on firmware it can handle one RGB/RGBW light or 4 independent monochrome light channels with gamma-corrected 12bit PWM. There are MOSFET's mounted on board which can handle up to 12V 1A load for each channel. If more power is needed a repeater is required.

Another useful feature is auxiliary power supply control output via optocoupler. Board may be powered from standby supply and LED power supply simultaneously.
