Questions
How big is the Negative supply PCB?
It measures 29.2 × 24.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Negative supply 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 Negative supply KiCad files?
From the cellularmitosis/breadboard-helpers repository on GitHub, at the commit this page was made from: the board is negative-supply/negative-supply.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Negative supply 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).
