Basic Schematic for Arduboy Clone

Hi.
Sorry for being a noob. Can anyone point me in the direction of basic schematics for the 3v and 5v DIY Arduboy. Is there a difference in board layout? I have a PCB design that works but I am just wanting to check out my design.

Thanks
Steve.

Search tool works a treat if you haven’t given it a go:

Theoretically the Arduboy should be built as 5v, it is underspec at 3v. Lowest recommended is using lipo battery voltage and that’s what’s shown in the official schematic.

Some people put in voltage boosters but there is no real reason to do so.

Slap! That is the sound of my hand hitting my face. If only I had scrolled a little further down the page. Thanks for that.
