Questions

How big is the Nav PCB?

It measures 40.3 × 36 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Nav use?

18 parts, built around the SN74LVC1G58DCK, AT24CS02-MAHM-T and SN74LVC1G0832DBV. 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 Nav KiCad files?

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

Can I use the Nav design in my own project?

Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
