They're both wireless and just plug and play or should i say. Bluetooth connect and play?
Yea no. They're plug and play. Lipo batteries cost too much.
I made these because i thought to myself why not!
So I made this!
Eye candy as always!
P.S BEFORE ANYONE TELLS ME THAT THE EXTRA SPACE IS UNNECESSARY. THAT EMPTY SPACE IS WHERE THE BATTERY WILL BE!
And that juicy BOM!

What parts does the DuoPad use?
7 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the DuoPad KiCad files?
From the OneForFreedom/DuoPad repository on GitHub, at the commit this page was made from: the board is KiCad/DuoPad.kicad_pcb and its schematic KiCad/DuoPad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
