Questions

How big is the Navdim PCB?

It measures 65 × 18 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Navdim use?

22 parts, built around the DMN2055UQ. 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 Navdim KiCad files?

From the jrmcauliffe/navdim repository on GitHub, at the commit this page was made from: the board is hardware/kicad/navdim/navdim.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Navdim design in my own project?

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