Key Features of DFRobot Gravity: Magnetic Latching Relay for ESP32 / Arduino
- Magnetic Latching (Bistable) Design: Maintains its ON or OFF state without continuous coil energization - dramatically reduces power consumption compared to standard relays.
- Near-Zero Standby Power: Consumes energy only during the brief switching pulse, making it perfect for battery-powered and solar-powered applications.
- High-Power Switching Capability: Handles loads up to AC 250V/5A and DC 30V/5A through SPDT (NO/NC/COM) screw terminals for versatile load control.
- Gravity Plug-and-Play Interface: Standard DFRobot Gravity 3-pin connector enables tool-free, solder-free connection to any Gravity-compatible controller board.
- Wide Voltage Compatibility: Operates at both 3.3V and 5V logic levels - natively compatible with ESP32, ESP8266, Arduino, Raspberry Pi GPIO, and more.
- Simple Digital Control: Toggle relay state with a single digital HIGH/LOW pulse from any GPIO pin - no complex driver circuits required.
- Onboard Status LED: Visual indication of current relay state for easy debugging and monitoring during development.
- Tech Depot India Screw Terminals: Secure, vibration-resistant high-voltage output connections for reliable long-term deployment.
