About this product

The 7Semi Single Channel I2C Relay Module makes it easy to control high-power devices using just two I2C wires. Whether you're building a smart home project, automating a pump, switching lights, or controlling other electrical equipment, this module lets your microcontroller safely turn devices ON and OFF.

The board supports both 3.3V and 5V operation, making it compatible with most popular development boards. It also features Qwiic/ STEMMA QT connectors for quick plug-and-play connections without soldering, while standard header pins are available for custom wiring.

Key Features

  • MCU-Friendly I²C Control: Uses SDA and SCL; compatible with Arduino, ESP32, Raspberry Pi, STM32 and RP2040.
  • Flexible Connectivity: Supports Qwiic/STEMMA QT, configurable I²C addressing, 5V input and a 3.3V/200 mA auxiliary output.
  • 10A SPDT Switching: Provides NO, COM and NC terminals, status LEDs, four mounting holes and a compact 53 × 26 mm design.
