In the world of flight simulation, space sims (Star Citizen, Elite Dangerous), and custom arcade controls, enthusiasts often find commercial hardware lacking. Whether you need a replica F-16 throttle, a helicopter collective, or specialized button boxes with rotaries and toggles, off-the-shelf products are either too expensive or don’t exist.

Enter MMJoy2 – a free, open-source firmware designed for the STM32F103C8T6 “Blue Pill” microcontroller board. Created by Megalight (Romanian developer MHeironimus), MMJoy2 turns a $3 microcontroller into a powerful, highly customizable USB HID joystick device with up to 128 buttons, 8 axes, 4 encoders, 2 POV hats, and even LED outputs.
