Questions
How big is the Rio octobot PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rio octobot use?
123 parts, built around the MAX485ED, ULN2803A, BC817 and WS2812B. 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 Rio octobot KiCad files?
From the multigcs/rio-octobot repository on GitHub, at the commit this page was made from: the board is rio-octobot.kicad_pcb and its schematic driver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rio octobot design in my own project?
Its repository states no licence, so its author keeps all rights: ask multigcs before reusing the design.
