    I need to create a new revision of an Adafruit Feather shield that is a high-frequency PWM RGB LED driver. The current design controls one common anode RGB LED with 3x N channel mosfets and PWM from a microcontroller. The new design I need help creating must now control two RGB LEDs. I also need to replace the terminal by which you connect to the LED control lines from 0.1" headers to a 4 co...
