Questions
How big is the SolarSystem PCB?
It measures 70 × 70 mm and has 2 copper layers, 0.8 mm thick.
What parts does the SolarSystem use?
65 parts, built around the ESP32-S3-MINI-1-N8, ISL89410IP, EL7202CN and MD8942. 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 SolarSystem KiCad files?
From the sijinhui/SolarSystem repository on GitHub, at the commit this page was made from: the board is PCB/Output/Output.kicad_pcb and its schematic Old-PCB/Access/Access.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SolarSystem design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
