Questions
How big is the MuscleRoller PCB?
It measures 70 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MuscleRoller use?
31 parts, built around the TL3315NF160Q. 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 MuscleRoller KiCad files?
From the SageRobots/RoboRoller repository on GitHub, at the commit this page was made from: the board is PCB/MuscleRoller.kicad_pcb and its schematic PCB/MuscleRoller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MuscleRoller design in my own project?
Its repository states no licence, so its author keeps all rights: ask SageRobots before reusing the design.
