# General Characteristics

2225
The **Modulino Buttons** module uses three tactile buttons and LEDs, which do not have native I²C capabilities. Instead, the buttons and LEDs are controlled by the Modulino's onboard microcontroller (STM32C011F4U6TR). This microcontroller provides I²C communication, allowing for flexible reading of button states and control of the LEDs. One unique feature of this setup is the ability to change the I²C address via software. This means the address can be modified based on your application needs, making it adaptable to different system configurations.
