Questions
How big is the Libreductioner PCB?
It measures 50.2 × 73 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Libreductioner use?
39 parts, built around the ATMEGA168A-AU, LM1117-5.0 and IRF3205. 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 Libreductioner KiCad files?
From the andreasb242/Libreductioner repository on GitHub, at the commit this page was made from: the board is Board/Libreductioner.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Libreductioner design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
