Questions
How big is the MCU module PCB?
It measures 47 × 34 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MCU module use?
23 parts, built around the LM1117MPX-3.3 and S8205A. 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 MCU module KiCad files?
From the eddyem/STM8_samples repository on GitHub, at the commit this page was made from: the board is microdrill/schematics/MCU_module.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the MCU module design in my own project?
Its repository states no licence, so its author keeps all rights: ask eddyem before reusing the design.
