Brad Robinson Posted April 14, 2017 Report Share Posted April 14, 2017 Hey all, Anyone know how much current I can safely draw from the 3.3 and 5V supplies on the Duo board. Looking to power 1x MAX7219 based 8x8 matrix module. Says max current draw is 2A, but I'm only going to be lighting a few leds and can dial down the brightness.
