Questions
How big is the Leddriver PCB?
It measures 180 × 128 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Leddriver use?
75 parts, built around the ATMEGA328P-AU, CH340G, HV9910CSG-G and S8050. 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 Leddriver KiCad files?
From the bitbyt3r/leddriver repository on GitHub, at the commit this page was made from: the board is leddriver.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Leddriver design in my own project?
Its repository states no licence, so its author keeps all rights: ask bitbyt3r before reusing the design.
