Fiddling with three LEDs with 10 legs total can be frustrating and leads to virtuos deadbug designs - resistors not even included, so today I took some time to design this pcb. The next design will be a board with an ULN2003A on, to drive the LEDs and an input board with three buttons and resistors, maybe in a sandwich methode, buttons on the upper side, driver on the bottom.
