Description The M5Stack M5StickC Joystick HAT is a compact joystick input module designed for M5StickC projects. It integrates an STM32F030F4P6 main control chip and communicates with the M5StickC host through the I2C interface. The joystick supports full-range directional deflection and a center button press. It outputs deflection angle data and switch digital signals, making the M5Stack M5StickC Joystick HAT useful for compact game controller interfaces, wireless joystick devices, and human-machine interaction input. With the unified HAT-series plug-in design, I2C address 0x38, and official software resources for Arduino, UIFlow, and EasyLoader, this Joystick HAT provides a simple way to add directional control to M5StickC-based prototypes. Features Joystick input: supports full-range directional deflection and center button press. STM32F030F4P6 MCU: built-in main control chip for joystick data handling. I2C communication: communicates with M5StickC through I2C at address 0x38. Angle and switch output: outputs deflection angle data and digital switch signals. M5StickC HAT design: uses the unified HAT-series plug-in structure for reliable connection. Software support: official resources are available for Arduino, UIFlow, EasyLoader, and protocol reference.
