Single-channel Relay for IoT Projects

This Graviton module pairs an ESP8266 Wi-Fi controller with a single relay rated for a 5-80V DC supply. It is designed for makers and integrators building custom smart-home or automation devices who need wireless switching of one external circuit from a compact development board.

Check Power Source and Load Compatibility

Verify that the device you intend to switch operates within the 5-80V DC range and that your power source can deliver sufficient current for both the relay coil and the ESP8266. Ensure your enclosure provides access for the antenna and that your firmware environment supports the ESP8266 toolchain before ordering.

Questions about this item

What comes in the box with the Graviton ESP8266 relay module?

The module is supplied as a single bare board with the ESP8266 chip and relay already soldered on; no enclosure, cables or power supply are included.

Should I choose a different voltage version or is the 5-80V range the only option?

The board operates across the full 5-80V DC range, so a single version covers every supply within those limits and no separate voltage model is needed.
