Last year we had some RBG balls in the mega tree, which we controlled with DC controllers. We noticed, that most DC controllers where overkill, they are designed to handle way more current then we needed (each ball was made of about 5 to 8 5050's. Each tree had 8 balls in it. So, we thought we would make a small dc controller to handle a "trees" worth of RGB balls (a total of 24 channels). Thought we would share the schematic for any feedback or comments. The two 485 inputs are unique to our SSD protocol, so that may seem unusually for some. NOTE: We have taken in the input from others and put the updated schematic on our site. We didn't want an incorrect schematic to stay up in case it causes confusion. Again, thanks for all the feedback.
