Questions
How big is the Pocket bob PCB?
It measures 104.1 × 58.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pocket bob use?
131 parts, built around the TPD3S014DBV. 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 Pocket bob KiCad files?
From the mwelling/pocket-bob repository on GitHub, at the commit this page was made from: the board is pocket-bob.kicad_pcb and its schematic pocket-bob.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pocket bob design in my own project?
Its repository states no licence, so its author keeps all rights: ask mwelling before reusing the design.
