Questions

How big is the Cool640xiao PCB?

It measures 257.4 × 103.1 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Cool640xiao use?

54 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 Cool640xiao KiCad files?

From the telzo2000/cool640 repository on GitHub, at the commit this page was made from: the board is kicad_cool640xiao/cool640xiao/cool640xiao.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Cool640xiao design in my own project?

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