Questions
How big is the Legacy PCB?
It measures 99 × 32 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Legacy use?
26 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 Legacy KiCad files?
From the Open-Visual-Stimulator/LED_driver repository on GitHub, at the commit this page was made from: the board is legacy/board/board.kicad_pcb and its schematic board/board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Legacy design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
