Questions

How big is the SegMan PCB?

It measures 121.9 × 83.8 mm and has 2 copper layers, 1.6 mm thick.

What parts does the SegMan use?

60 parts, built around the V7805-500, T9AS1D12-24, BSS138W and S1B. 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 SegMan KiCad files?

From the Lafayette-FSAE/SegMan repository on GitHub, at the commit this page was made from: the board is SegMan.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the SegMan design in my own project?

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