Questions
How big is the Stm8l dev PCB?
It measures 44.5 × 71.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Stm8l dev use?
42 parts, built around the STM8L151C8T6, AMS1117-3.3 and B5819W. 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 Stm8l dev KiCad files?
From the suuppl/stm8l-dev repository on GitHub, at the commit this page was made from: the board is electronics/hw/stm8l-dev.kicad_pcb and its schematic electronics/hw/stm8l-dev.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stm8l dev design in my own project?
Its repository publishes it under the EUPL-1.2 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
