Questions
How big is the Ww2020 PCB?
It measures 65.6 × 56 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ww2020 use?
69 parts, built around the LMZ22005TZ, DRV8871DDA, PCA9685PW and WS2812B-5050RGB. 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 Ww2020 KiCad files?
From the dkjonas/WildWillyHardware repository on GitHub, at the commit this page was made from: the board is Rover2021/ww2020.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ww2020 design in my own project?
Its repository states no licence, so its author keeps all rights: ask dkjonas before reusing the design.
