Questions
How big is the EPS PCB?
It measures 80 × 80 mm and has 4 copper layers, 1.6 mm thick.
What parts does the EPS use?
243 parts, built around the TCAN3414D, TPS22995EVM, 74LVC2G07GV and TPL5010EVM. 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 4111Spyglass/Hardware_CSAT repository on GitHub, at the commit this page was made from: the board is eps_board/EPS.kicad_pcb and its schematic aux_board/aux_board.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 4111Spyglass before reusing the design.
