Questions
How big is the Strg m PCB?
It measures 60.7 × 128.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Strg m use?
40 parts, built around the LM324. 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 Strg m KiCad files?
From the backtail/strg-m repository on GitHub, at the commit this page was made from: the board is KiCad_Project/strg+m.kicad_pcb and its schematic KiCad_Project/strg+m interface.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Strg m design in my own project?
Its repository states no licence, so its author keeps all rights: ask backtail before reusing the design.
