Questions
How big is the SEM PCB?
It measures 64.5 × 56.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SEM use?
24 parts, built around the ESP32-WROOM-32, ACPL-214-500E and AMS1117-3.3. 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 SEM KiCad files?
From the Sani7/SEM repository on GitHub, at the commit this page was made from: the board is KiCad/SEM/SEM.kicad_pcb and its schematic KiCad/Display/Display.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SEM 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).
