README
README.mdWelcome to the MicroMouse project kiCAD files of Chidochashe Kufakunesu ( KFKCHI001) and Danella Oelofse ( OLFDAN001 )
The folder titled 'FinalMicroMouseFiles' is the final version of our project and the version that was submitted to UCT. It includes a screenshot of the JLCPCB cart, the BOM, the positions file, as well as the gerber and drill files from kiCAD.
The zip folder is the kiCAD gerber files that were submitted to JLCPCB for manufacturing.
The pdf entitled 'FinalSchematic' is the schematic of our entire solution for the power subsystem.

Questions
How big is the FinalMicroMouseFiles PCB?
It measures 82 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FinalMicroMouseFiles use?
56 parts, built around the CH224K, DRV8833PWP, TPS22918DBV and AP2112K-3.3. 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 FinalMicroMouseFiles KiCad files?
From the Eng-Claire/power_sub_systems repository on GitHub, at the commit this page was made from: the board is FinalMicroMouseFiles/MM.kicad_pcb and its schematic FinalMicroMouseFiles/MM.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FinalMicroMouseFiles design in my own project?
Its repository states no licence, so its author keeps all rights: ask Eng-Claire before reusing the design.
