I'm working on an arcade joystick with full analog capability using a Hall effect sensor. It's along the lines of the Ultimarc Ultrastik, which I'm currently using, but it has so many shortcomings that I decided to build my own. I decided to go with a rp2350 microcontroller, and it will have inputs for 16 buttons, and outputs for RGB leds for every button. It should be a direct swap for any enclosure designed for a modern Sanwa stick, which it's based on.
