Here are different sets of PCBs for various Micro Mouse applications. This is the start of me using KiCad. I make no promises that any of this works.
Some of these boards (MouseSMDUKMARSAdvancedBoard and MouseMainboardTemplate) started as UKMARS boards that can be found Here

Circuit design for the other boards is credited to Duncan Louttit
