About this product

The 7Semi Dual Channel I²C Relay Module enables independent control of two electrical loads using only the SDA and SCL pins. Featuring two 10 A SPDT relays, Qwiic/STEMMA QT connectivity and configurable I²C addressing, it integrates easily with Arduino, ESP32, Raspberry Pi, STM32 and RP2040 boards. It is ideal for home automation, robotics, IoT and industrial control applications.

Key Features

  • Dual 10 A SPDT Relays: Independently control two compatible AC or DC loads through NO, COM and NC terminals.
  • Simple I²C Control: Uses only SDA and SCL pins, reducing the number of MCU GPIO pins required.
  • Broad Compatibility: Works with 3.3V and 5V I²C systems, including Arduino, ESP32, Raspberry Pi, STM32 and RP2040.
  • Easy Integration: Includes Qwiic/STEMMA QT connectors, configurable I²C addressing and power/relay status LEDs.
  • Selectable I2C address at bottom with default address at 0x20
