Questions
How big is the Secondorderbasic PCB?
It measures 72 × 71 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Secondorderbasic use?
10 parts, built around the OP1177ARMZ. 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 Secondorderbasic KiCad files?
From the zaneakers/1layerLowPassSallenKeyPCB repository on GitHub, at the commit this page was made from: the board is secondorderbasic/secondorderbasic-backups/secondorderbasic-2025-05-27_163612/secondorderbasic.kicad_pcb and its schematic secondorderbasic/secondorderbasic-backups/secondorderbasic-2025-05-27_163612/secondorderbasic.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Secondorderbasic 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).
