Questions
How big is the Frankii round 2 PCB?
It measures 96.5 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Frankii round 2 use?
35 parts, built around the DRV8871DDA and B3B-XH-A. 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 Frankii round 2 KiCad files?
From the JonathanJia05/Robot-sumo repository on GitHub, at the commit this page was made from: the board is frankii round 2/frankii round 2.kicad_pcb and its schematic frankii round 2/frankii round 2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Frankii round 2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask JonathanJia05 before reusing the design.
