Questions

How big is the OpenTag PCB?

It measures 120 × 70 mm and has 2 copper layers, 1.6 mm thick.

What parts does the OpenTag use?

7 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 OpenTag KiCad files?

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

Can I use the OpenTag design in my own project?

Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
