Questions

How big is the SUPERMUSCLE PCB?

It measures 83 × 96 mm and has 2 copper layers, 1.6 mm thick.

What parts does the SUPERMUSCLE use?

51 parts, built around the TEENSY 4.1. 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 SUPERMUSCLE KiCad files?

From the dunland/muscle repository on GitHub, at the commit this page was made from: the board is hardware/ECAD/SUPERMUSCLE/SUPERMUSCLE.kicad_pcb and its schematic hardware/ECAD/SUPERMUSCLE/SUPERMUSCLE.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the SUPERMUSCLE design in my own project?

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