Questions

How big is the Lfo stomp v1 panelized PCB?

It measures 67 × 100 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Lfo stomp v1 panelized use?

100 parts, built around the TL072 and BC547. 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 Lfo stomp v1 panelized KiCad files?

From the EchelonForce/lfo_stomp repository on GitHub, at the commit this page was made from: the board is lfo_stomp_v1/lfo_stomp_v1_panelized.kicad_pcb and its schematic lfo_stomp_v1/lfo_stomp_v1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Lfo stomp v1 panelized design in my own project?

Its repository states no licence, so its author keeps all rights: ask EchelonForce before reusing the design.
