Questions
How big is the UglyBob PCB?
It measures 73 × 46 mm and has 4 copper layers, 0.8 mm thick.
What parts does the UglyBob use?
70 parts, built around the PMV15ENER, TPS7A2033PDBVR-TP, ICM-42688-V and SFH 313FA. 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 UglyBob KiCad files?
From the StaRadian/uglyBob repository on GitHub, at the commit this page was made from: the board is hardware/kicad/uglyBob/uglyBob.kicad_pcb and its schematic hardware/kicad/uglyBob/interface.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the UglyBob design in my own project?
Its repository states no licence, so its author keeps all rights: ask StaRadian before reusing the design.
