Questions
How big is the July23 PCB?
It measures 109.5 × 74 mm and has 2 copper layers, 1.6 mm thick.
What parts does the July23 use?
67 parts, built around the LM358, NCR405UX, CD74HC4067M and MC78M05CDTG. 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 July23 KiCad files?
From the biofoundry/lampdiagnosticspcb repository on GitHub, at the commit this page was made from: the board is July23.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the July23 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).
