Need to switch a circuit on or off and have it stay that way even after power drops? The DFRobot Gravity: Magnetic Latching Relay for ESP32 / Arduino does that job, and it's available at Rs 855 from Tech Depot India — order the DFRobot Gravity Magnetic Latching Relay directly from our store.
What is the DFRobot Gravity Magnetic Latching Relay?
It's a relay module from DFRobot's Gravity line, built to work with ESP32 and Arduino boards. The key word is "latching" — a latching relay holds its last position (on or off) using a magnetic mechanism, rather than needing continuous power to stay in that state. That's a different behaviour from a standard relay, which typically needs power applied the whole time to stay switched on.
Because it's part of the Gravity range, it's designed to connect up cleanly with compatible ESP32 and Arduino boards. Confirm exact connector and interface details on the product page before you plan your wiring.
DFRobot Gravity Magnetic Latching Relay projects — what you can build
- A power-efficient switch for a device that needs to hold its state without constant current draw
- A remote on/off controller for lighting or a small appliance, driven from an ESP32 or Arduino
- A battery-powered automation node where every milliamp of standby power matters
- A latching control point in a larger home automation setup
- A fail-safe switch that keeps its last state even through a brief power interruption

| 8 Channel Isolated 5V 10A Relay Module opto coupler For Arduino PIC AVR DSP ARM | Rs 310 | 8-channel opto-isolated relay module rated to 10A |
Choosing the right relay for your project
If your project only needs to switch one load and hold its state without drawing standby power, the DFRobot Gravity Magnetic Latching Relay is the more targeted pick. If you instead need to control several independent loads at once, a multi-channel relay board from the comparison table above may fit better. Either way, match the relay's rated voltage and current to your actual load before wiring anything up.
Double-check pin mapping and control logic against both the product page and your ESP32 or Arduino board's documentation, since incorrect wiring on a relay circuit can damage your controller.
