Questions
How big is the Lightpad PCB?
It measures 76.2 × 118.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lightpad use?
43 parts, built around the ATMEGA32U4-MU, SRV05-4 and 1N4148W. 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 Lightpad KiCad files?
From the Aeonstrife/lightpad repository on GitHub, at the commit this page was made from: the board is lightpad.kicad_pcb and its schematic lightpad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lightpad design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
