My motivation was to create a fightstick that I could play fighitng games like Street Fighter. Although my fight stick worked perfectly on emulators, it did not register properly on Steam. Because I could not get the fightstick to work, I figured that if I created a hid keyboard device then steam should be able to register the commands properly.

I sent the gerber files from circuit maker to JLCPCB and got my board printed out and shipped.
