So called "leverless" controllers are popular among fighting game enthusiasts for their speed and accuracy compared to traditional lever-style joysticks. You can build your own with the Adafruit QT Py RP2040 and GP2040-CE firmware.
Mini arcade buttons are mounted to a 3D printed case (or BYOB(ox)) to make for a playable, ergonomic design. And by wiring the buttons to the QT Py Terminal Block BFF using quick-connect cables, you can keep the build manageable and nearly solder-free -- the only soldering required is the QT Py header pins.
Since the GP2040-CE firmware can be configured from a web browser, this project is essentially code free -- just drag and drop the UF2 and you're ready to play.
