Questions
How big is the Pixl.js PCB?
It measures 32.2 × 23 mm and has 4 copper layers, 1.2 mm thick.
What parts does the Pixl.js use?
88 parts, built around the TPS61040DBV, MH254ESQ, TP4055 and XC6206P332MR. 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 Pixl.js KiCad files?
From the xiaohail/pixl.js-oled repository on GitHub, at the commit this page was made from: the board is pixl.js.kicad_pcb and its schematic pixl.js.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pixl.js design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
