Questions
How big is the DroidPad PCB?
It measures 170.2 × 218.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DroidPad use?
109 parts, built around the ATMEGA88A-AU. 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 DroidPad KiCad files?
From the mackemint/Midi-Controller-PCB-Layout repository on GitHub, at the commit this page was made from: the board is DroidPad.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the DroidPad design in my own project?
Its repository states no licence, so its author keeps all rights: ask mackemint before reusing the design.
