Questions
How big is the Microbot v1.1 PCB?
It measures 185 × 58.6 mm and has 4 copper layers, 2 mm thick.
What parts does the Microbot v1.1 use?
390 parts, built around the 74LVC2G17GW, OH137, ADS1015IDGS and DRV8834PWP. 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 Microbot v1.1 KiCad files?
From the Freimor/HRDW-Microbot repository on GitHub, at the commit this page was made from: the board is KiCAD/Microbot_v1.1.kicad_pcb and its schematic KiCAD/BackPCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Microbot v1.1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Freimor before reusing the design.
