Control a 12V led string

The 12V Christmas lights needed be powered and controlled. I chose to buy a Mean Well RS-50-12 that delivers 12V up to 4.2A (50W) and built an enclosure. (material for another article). In this post I describe how I created the controller.

PS: This project is still in progress….

The basis is a 3x7cm prototype PCB and I added two rows of 8x female header pins for the Microcontroller, four 2x male header pins for the Low-dropout regulator and two KF301-5.0 screw terminal blocks for the input of 12V and ground from the power supply and the ouput of 12V, ground and data to the led string.

Used items:
3x7cm prototype PCB
Single row female pin header 2.54mm
Single row male pin header 2.54mm
50pcs 12V WS2811 12mm Christmas IP68 waterproof led string
xm1584 step-down power supply
SM 2.54mm pitch 3 pin connector
