Description
The Gravity: Easy Relay Module is a beginner-friendly switching board designed to simplify relay wiring for electronics projects. Featuring plug-and-play DC2.1 connectors and a standard 3-pin interface, it is ideal for students, makers, and hobbyists building smart home systems, robotics, and automated lighting.
Simplified DC power connectivity
Traditional relay screw terminals are replaced with standard DC2.1 input and output jacks for quick and secure setup. The module connects directly to battery boxes, DC power supplies, and power banks using the included adapters.
Hardware mode switch and status LED
An onboard toggle switch lets you switch between Normally Open (NO) and Normally Closed (NC) modes without rewiring your circuit. An integrated LED provides clear visual feedback of the current output state.
Wide logic voltage support
Operating with a logic supply and signal voltage of 3.3V to 5.5V, this module communicates seamlessly with 3.3V and 5V microcontrollers like Arduino and other development boards via a standard Gravity digital cable.
Load capacity and switching performance
The module handles an input operating voltage from 5V to 30V with continuous currents up to 2.5A. It offers high-speed switching characteristics with a 20us turn-on time, 50us turn-off time, and a 1kHz switching frequency.
Comprehensive accessory kit included
Each unit comes with a digital sensor cable, a black acrylic mounting base with M3 screws, and a variety of DC2.1 and USB power adapter cables to suit diverse project setups.
