Gravity I2C RGB LED Button Module

This is an I2C button module with controllable RGB LED backlight. The module not only supports reading key status like traditional keys, but also controlling the RGB LED color and independently turning the light on and off, allowing you to create more visual and interactive experiences for your projects. For example, when the system prompts the user to press the button, the RGB light blinks green; when the button is pressed, the light turns red. This module has a built-in 3-bit DIP switch for setting 8 different I2C addresses, so that up to 8 such button modules can be cascaded without occupying additional ports.
