Questions
How big is the Distortion 01 PCB?
It measures 54 × 99.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Distortion 01 use?
107 parts, built around the TL072, BAS21, BS170 and DTC114Y. 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 Distortion 01 KiCad files?
From the Randagodron/satelyte repository on GitHub, at the commit this page was made from: the board is cad/distortion_01.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Distortion 01 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Randagodron before reusing the design.
