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)

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.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
