This repository uses the SFU Satellite Team's KiCad component library as a submodule. To start working on the repository:

text
1. Open the git shell
2. Navigate to the directory you wish to place the repository inside
3. git clone --recursive "https://github.com/SFUSatClub/eps-hardware.git"
4. cd .\eps-hardware\KiCad-Lib\
5. git checkout master

If you modify either the component schematic or footprint libraries you must push those changes to the SFUSatClub/KiCad-Lib repository.

Questions

How big is the Eps PCB?

It measures 95.9 × 90.2 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Eps use?

194 parts, built around the B3B-XH-A(LF)(SN), TPS22967DSG, CSD17551Q3A and BAT54HT1G. 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 SFUSatClub/eps-hardware repository on GitHub, at the commit this page was made from: the board is eps.kicad_pcb. 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 SFUSatClub before reusing the design.
