Questions
How big is the Ember pcb PCB?
It measures 119.3 × 99.9 mm and has 12 copper layers, 1.62 mm thick.
What parts does the Ember pcb use?
37 parts, built around the LP5912-0.9DRV, LP5912-1.1DRVR and LP5912-2.5DRV. 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 Ember pcb KiCad files?
From the akashlevy/ember-pcb repository on GitHub, at the commit this page was made from: the board is ember-pcb.kicad_pcb and its schematic ember-pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ember 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).
