This is an I2C button module with RGB LED. The module not only supports reading button status like conventional ones, but also controlling RGB LED color and switching on/off the light independently, which could create more visual and interactive experiences for your projects. For example, when the system prompts users to press the button, the RGB light blinks in green; when the button is pressed, the light turns red.

This module has an onboard 3-bit DIP switch for setting 8 different I2C addresses, which means up to 8 such button modules can be cascaded together without occupying additional ports.

Features

High-quality button, mechanical keyboard-like tactile feedback

Soft and even color light

Independent control of RGB LED, eight I2C addresses can be set

Double I2C ports for simple cascade

On-board interrupt interface for highly real-time tasks

Applications

Simulated Elevator Buttons

Mini Matrix Keyboard

IoT Projects

DIY Electronic Projects

Jargon buster

Plain-language definitions for the technical terms used above.

DC: DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
DIP switch: A DIP switch is a small set of physical on/off switches used to configure hardware settings without software. It matters because changing features such as auto power-on or charging limits may require moving these tiny switches correctly.
Gravity: Gravity is DFRobot’s plug-in connector system for sensors, motors and modules, using standard cables to reduce loose jumper wiring. It matters because Gravity-compatible parts can connect directly to these ports, while non-Gravity parts may need adapters or manual wiring.
I2C: I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
IoT: Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
LED: A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
RGB: Short for red, green and blue, the three primary colours of light that are mixed in varying amounts to make a wide range of colours. In electronics RGB can refer to an LED or pixel that blends these three colours, or to a colour signal or interface that carries separate red, green and blue channels.
UART: UART is a simple asynchronous serial interface that sends data over separate transmit and receive wires, usually labelled TX and RX, with both ends set to the same baud rate. It is a common way for microcontrollers and other serial devices to exchange data.
