Questions
What parts does the SwarmBot use?
81 parts, built around the ESP32-D0WD, MAX7313ATG+, STSPIN220 and XM25QH32BHIG. 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 SwarmBot KiCad files?
From the keionbis/Vision-Robot-Electronics repository on GitHub, at the commit this page was made from: the board is SwarmBotTop/SwarmBot.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the SwarmBot design in my own project?
Its repository states no licence, so its author keeps all rights: ask keionbis before reusing the design.
