Questions

How big is the Drn2 PCB?

It measures 76.2 × 70 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Drn2 use?

61 parts, built around the ADS1115IDGS and LSM9DS1. 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 Drn2 KiCad files?

From the Ekter/drn repository on GitHub, at the commit this page was made from: the board is drn2/drn2.kicad_pcb and its schematic drn2/drn2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Drn2 design in my own project?

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