Questions
How big is the Front pcb PCB?
It measures 120 × 160 mm and has 2 copper layers, 0.8 mm thick.
What parts does the Front pcb use?
13 parts, built around the MPR121QR2 and EVQPUJ02K. 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 Front pcb KiCad files?
From the zephray/Preader repository on GitHub, at the commit this page was made from: the board is hardware/front_pcb/front_pcb.kicad_pcb and its schematic hardware/front_pcb/front_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Front pcb 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).
