Questions

How big is the Cesar-3 PCB?

It measures 304.2 × 117.9 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Cesar-3 use?

100 parts. 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 Cesar-3 KiCad files?

From the nucatus/cesar repository on GitHub, at the commit this page was made from: the board is cesar-3.kicad_pcb and its schematic cesar-3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Cesar-3 design in my own project?

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