Questions
How big is the Stomp 01 PCB?
It measures 54 × 104 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Stomp 01 use?
93 parts, built around the TEENSY 4.1, SGTL5000XNLA3, TL072 and TPS54331DR-JSM. 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 Stomp 01 KiCad files?
From the mattybrad/omnistomp repository on GitHub, at the commit this page was made from: the board is pcb/stomp_01/stomp_01.kicad_pcb and its schematic pcb/stomp_00/analoginput.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stomp 01 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).
