Questions
How big is the Stm32l053c PCB?
It measures 26.7 × 43.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Stm32l053c use?
45 parts, built around the AP2112K-3.3. 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 Stm32l053c KiCad files?
From the theapi/solar repository on GitHub, at the commit this page was made from: the board is Mk3/kicad/stm32l053c.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stm32l053c 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).
