It turns out that the last day of the year can be quite productive. I’ve managed to sneak in a PCB layout for the input measurement and protection board for my sunpowered. Got it ordered, can’t wait to test it ! I got carried away with via stitching there a bit - we’ll see how hard it will be to solder the larger components because of that. The whole project is hosted here - it’s open hardware so please do take a look.
