    4242Some boards (consult the board user manual) use a bi-color LED (typical green/red) where 2 GPIO's are used (connected to each side of the LED). In this scenario setting one LED on and the other Off would produce one color and flipping them would produce the other (while turning them both on or both off would result in no LED's lit):
