And our website (quite empty yet :/ ) here :https://associationrobottelecomstrasbourg.github.io/
MainBotPCB is the PCB that will contain the majority of the components and connections required for our main robot to work, hence the original name :) .

Questions
How big is the MainBot PCB?
It measures 116 × 122.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MainBot use?
99 parts, built around the DRV8825PWP, ISL85410FRZ and TCA9548APW. 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 MainBot KiCad files?
From the ArnaudSchlumberger/MainBotPCB repository on GitHub, at the commit this page was made from: the board is Kicad/MainBot/MainBoard/MainBoard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the MainBot design in my own project?
Its repository states no licence, so its author keeps all rights: ask ArnaudSchlumberger before reusing the design.
