The DFRobot Gravity Digital Push Button (Green) is a simple momentary switch with an on-board LED indicator, designed for the Gravity interface system. It features an immersion gold PCB surface, a bright green cap, and a standard 3-pin digital connector for plug-and-play use with Arduino and other microcontrollers.
A "D" marking on the board clearly identifies it as a digital sensor, and the wide 3.3–5 V operating range ensures compatibility with most development boards.
Key Features
- Gravity Digital Interface – Standard 3-pin connector for plug-and-play wiring
- On-Board LED Indicator – Visual feedback when the button is pressed
- Wide Voltage Range – Compatible with 3.3 V and 5 V controllers
- Immersion Gold PCB – Corrosion-resistant surface finish for long-term reliability
- Removable Green Cap – Bright coloured button cap with satisfying tactile feel
- Standard Mounting – Two 3 mm mounting holes on 5 mm spacing
Specifications
- Supply Voltage – 3.3–5 V
- Interface – Digital (Gravity 3-pin)
- Dimensions – 22 × 30 mm
Package Contents
- 1× Digital push button (green)
- 1× Digital cable

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 is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
