The Gravity Digital Push Button (Blue) is a simple momentary push button module designed for the DFRobot Gravity interface. It features an onboard LED indicator, immersion gold PCB surface, and a coloured button cap. A "D" marking on the board identifies it as a digital sensor for quick wiring reference.
Compatible with 3.3 V and 5 V systems, it connects via the standard Gravity 3-pin digital interface for plug-and-play use with Arduino and other microcontroller boards.
Key Features

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.
- 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.
