Questions
How big is the Micromouse pcb PCB?
It measures 60 × 90 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Micromouse pcb use?
69 parts, built around the ESP32-S3-WROOM-1-N8, L293D, AMS1117-3.3 and BC547. 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 pcb KiCad files?
From the IvarNilsson/MicroMouse repository on GitHub, at the commit this page was made from: the board is pcb/micromouse/micromouse_pcb/micromouse_pcb.kicad_pcb and its schematic pcb/all_main/main_pcb/main_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Micromouse pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask IvarNilsson before reusing the design.
