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
- Wide Voltage Range – 3.3 V to 5 V operation
- Onboard LED – Visual indicator for button state

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.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- 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.
