Questions

How big is the ECE477 PCB?

It measures 96.5 × 88.9 mm and has 2 copper layers, 1.6 mm thick.

What parts does the ECE477 use?

78 parts, built around the P7805-2000-S. 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 ECE477 KiCad files?

From the jpanos/ECE477-PCB repository on GitHub, at the commit this page was made from: the board is ECE477.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the ECE477 design in my own project?

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