Re: 5V tolerance

Going forward, do you guys think you'll officially support 5v tolerance? It would be a nice feature to have and make interfacing much easier in many cases. There is like a bazillion of devices out there that do this for super low cost. Ever since the first micros that went from 5v to 3.3v this issu...

Re: CMAKE how to use typedef enum declared in component

From the bottom side of your PCB, insert the headers through until they just hit the top edge of the D1 then solder them from each side and snip off the excess. I.E. your just using th...
