README
README.mdCompetitionProStarMini
A replacement PCB for the Competition Pro Mini and Pro Star Mini (with autofire) Joysticks to easily replace failing microswitches with modern parts.

The Saia-Burgess F4T7-UL Microswitches used in this design provide up to 10 000 000 cycles of operation and allow the original stick gate to remain in place, giving the best overall experience.
A bent piece of copper wire can be used to further secure the directional switches to the pcb, using the provided mounting holes.

Questions
How big is the CompetitionProStarMini PCB?
It measures 59 × 76.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CompetitionProStarMini use?
18 parts. 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 CompetitionProStarMini KiCad files?
From the InsaneDruid/CompetitionProStarMini repository on GitHub, at the commit this page was made from: the board is competitionProStarMini.kicad_pcb and its schematic competitionProStarMini.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CompetitionProStarMini design in my own project?
Its repository states no licence, so its author keeps all rights: ask InsaneDruid before reusing the design.
