Questions
How big is the STS1 EPS 1 PCB?
It measures 81 × 85 mm and has 6 copper layers, 1.6 mm thick.
What parts does the STS1 EPS 1 use?
185 parts, built around the TPS259472ARPW, LM334M, LTC4451AV#TRMPBF and SI7272DP-T1-GE3-VB. 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 EPS 1 KiCad files?
From the SpaceTeam/STS1_EPS repository on GitHub, at the commit this page was made from: the board is pcbs/STS1_EPS_1.kicad_pcb and its schematic pcbs/STS1_EPS_1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the STS1 EPS 1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask SpaceTeam before reusing the design.
