    I am looking for someone to design a simple high side PWM circuit. This will be running at 12-15vdc and could theoretically have a load of 15A max. It can't be low side because the negative terminal of my PWM controlled device is grounded to the frame. I prefer Kicad, or Fritzing as those two are easiest for me to customize my board layout in. If you can make the circuit entirely using digike...
