Questions
How big is the Vrb PCB?
It measures 82 × 75 mm and has 6 copper layers, 1.6 mm thick.
What parts does the Vrb use?
227 parts, built around the TJA1051TK/3/1J, I3A4W008A033V-001-R, TPS2116DRL and PZU24B2A. 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 Vrb KiCad files?
From the Poppy-Robotics/vrb repository on GitHub, at the commit this page was made from: the board is vrb.kicad_pcb and its schematic can.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Vrb design in my own project?
Its repository states no licence, so its author keeps all rights: ask Poppy-Robotics before reusing the design.
