I’ve haven’t been well for a couple of weeks with recurring sinusitis. Consequentially work on the Mini has dragged to a halt… well nearly. I’ve created a PCB for the controller and I’ll let the pretty pictures tell the story.
I’ll etch up a few copies of the board next week hopefully when I have three days off from work. By the way the layout and 3D I did in Kicad, first PCB I’ve done since the early 90’s.

Changed board to have larger holes and pads for high current stuff, also added Bi-colour LED facility (to give it some bling!) Updated all pictures to reflect changes.

Sometimes it pays to re-read what you have posted! For further clarity, the Red/Green LED will be glowing red when 0% PWM is happening, and then will progressively go through orange to green when 100% PWM.
I’ll be making the PCB’s tomorrow… so stay tuned.
