Questions
How big is the STS1 EEE PCB?
It measures 81.1 × 85 mm and has 4 copper layers, 1.6 mm thick.
What parts does the STS1 EEE use?
43 parts, built around the MP28167GQ-P, AQ1003-01LTG and UCLAMP0871P.TNT. 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 STS1 EEE KiCad files?
From the SpaceTeam/STS1_EEE repository on GitHub, at the commit this page was made from: the board is STS1_EEE.kicad_pcb and its schematic STS1_EEE.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the STS1 EEE design in my own project?
Its repository states no licence, so its author keeps all rights: ask SpaceTeam before reusing the design.
