Questions
How big is the Robot b0 PCB?
It measures 48.3 × 46 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Robot b0 use?
51 parts, built around the REG1117, MINI-USB-5P and RJ45. 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 Robot b0 KiCad files?
From the koson/hometether repository on GitHub, at the commit this page was made from: the board is kicad/robot/robot-b0.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Robot b0 design in my own project?
Its repository states no licence, so its author keeps all rights: ask koson before reusing the design.
