I found that off the shelf products for LED strips for what I wanted to do were all lacking in some way.
I wanted something to control LED strips mounted in a crown molding around the top of the walls for indirect lighting. I ended up buying some circuit boards from Ebay and soldering them up. I needed 24V and about 10A total, broken into 2 x 5A sections, and not much out there could do it. The board is 5 channels and ESP8266 based so I’m using ESPhome on it.
