Universal One-Handed Controller

A compact wireless controller built around the ESP32-C3 Super Mini — featuring a single joystick and one button on top, with a rechargeable battery system.

I designed the custom PCB, handled all the wiring and circuit connections, and wrote the firmware that processes input and communicates with connected devices. The 3D-printed housing was designed by someone else.

The goal was to build something reusable — a reliable input device I could plug into multiple projects without rebuilding the hardware every time.
