This compact illuminated push-button module adds a simple, visible input to interactive electronics, classroom prototypes and maker projects. A transparent cap shows the integrated LED, which lights as soon as the button is pressed for clear visual feedback.
It uses the Gravity PH2.0-3P connector for straightforward plug-and-play wiring with compatible expansion boards and controllers. The module outputs High when pressed and Low when released, making it easy to read as a digital input from platforms such as micro:bit and other microcontroller projects.
The green version is supplied with the LED button module and a digital sensor connector, making it suitable for control panels, robotics interfaces, interactive displays and STEM demonstrations.
Features:
- Integrated LED indicator lights when the button is pressed
- Digital signal output for simple microcontroller input detection
- Gravity PH2.0‑3P connector for plug‑and‑play wiring
- Multiple LED color options: red, yellow, green, blue, and white
- Compact design suitable for interactive electronics projects
Specifications:
- Operating Voltage: +3.3-5V (3.3V is recommended)
- Output: digital
- Connector: PH2.0-3P
- Dimension: 27×26.5mm/1.06×1.04”
- Colors Available: red, yellow, green, blue, white
A handy choice for adding tactile input with instant visual indication to beginner-friendly hardware experiments and creative computing builds.
Jargon buster
Plain-language definitions for the technical terms used above.
- 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.
- 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.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
