Questions
How big is the Trivial lm399 PCB?
It measures 49.5 × 49.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Trivial lm399 use?
27 parts, built around the TL062. 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 Trivial lm399 KiCad files?
From the cellularmitosis/basic-lm399 repository on GitHub, at the commit this page was made from: the board is kicad/trivial-lm399.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Trivial lm399 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).
