Questions
How big is the STM PCB?
It measures 106.1 × 132 mm and has 4 copper layers, 1.6 mm thick.
What parts does the STM use?
128 parts, built around the TL072 and ADG419BR. 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 STM KiCad files?
From the annegautham/STM repository on GitHub, at the commit this page was made from: the board is Mainboard/Mainboard.kicad_pcb and its schematic Mainboard/ADC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the STM 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).
