Questions
How big is the Micromouse PCB?
It measures 109.2 × 76.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Micromouse use?
17 parts, built around the VL53L0X, ADXL335BCP and IRFZ44N. 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 Micromouse KiCad files?
From the PolyEd/MicroMouse repository on GitHub, at the commit this page was made from: the board is Micromouse2/Micromouse.kicad_pcb and its schematic Micromouse2/Micromouse.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Micromouse design in my own project?
Its repository states no licence, so its author keeps all rights: ask PolyEd before reusing the design.
