Questions

How big is the Eps PCB?

It measures 89.4 × 99.3 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Eps use?

169 parts, built around the AO6608, AD5259BRMZ100, LTC2943CDD and CSD16403Q5A. 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 Eps KiCad files?

From the UWCubeSat/EPS repository on GitHub, at the commit this page was made from: the board is eps/eps.kicad_pcb and its schematic testing boards/CurrentMeasuringWithProtection/CurrentMeasuringWithProtection.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Eps design in my own project?

Its repository states no licence, so its author keeps all rights: ask UWCubeSat before reusing the design.
