Questions
How big is the LedArray9 PCB?
It measures 7.6 × 22.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LedArray9 use?
19 parts. 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 LedArray9 KiCad files?
From the CalSol/braintrain repository on GitHub, at the commit this page was made from: the board is ledarray/LedArray9.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LedArray9 design in my own project?
Its repository publishes it under the BSD-3-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
