Questions
How big is the Ur10 PCB?
It measures 65 × 35 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ur10 use?
18 parts, built around the AO3401A. 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 Ur10 KiCad files?
From the kmzbrnoI/ur10 repository on GitHub, at the commit this page was made from: the board is ur10.kicad_pcb and its schematic ur10.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ur10 design in my own project?
Its repository states no licence, so its author keeps all rights: ask kmzbrnoI before reusing the design.
