Questions
How big is the FitBot PCB?
It measures 118.1 × 90.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FitBot use?
37 parts, built around the L298N and LM2596T-5.0. 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 FitBot KiCad files?
From the redixhumayun/pcb-design repository on GitHub, at the commit this page was made from: the board is FitBot/FitBot.kicad_pcb and its schematic FitBot/FitBot.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FitBot design in my own project?
Its repository states no licence, so its author keeps all rights: ask redixhumayun before reusing the design.
