Questions
How big is the Ledmatrix PCB?
It measures 27 × 80 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Ledmatrix use?
276 parts, built around the AP2112K-1.8, M24C02-FDW6TP and UMH3N. 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 Ledmatrix KiCad files?
From the bitluni/Mdot2Matrix repository on GitHub, at the commit this page was made from: the board is pcb/ledmatrix/ledmatrix.kicad_pcb and its schematic pcb/ledmatrix/ledmatrix.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ledmatrix 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).
