Questions

How big is the Offset PCB?

It measures 70.8 × 104.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Offset use?

51 parts, built around the TL072. 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 Offset KiCad files?

From the MatthewATaylor/Modular-Synth-Hardware repository on GitHub, at the commit this page was made from: the board is Offset/Offset.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Offset 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).
