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.
