7Semi Dual Channel 5V 10A I2C Qwiic Relay Module
The 7Semi Dual Channel 5V 10A I2C Qwiic Relay Module is a convenient 2-channel I²C relay board designed for controlling two electrical loads independently from a compatible microcontroller or development board. It features two 10A SPDT relays, providing a practical solution for switching higher-power AC or DC devices while keeping the control interface simple.
Communication is handled through the I²C interface using SDA and SCL, reducing the number of GPIO pins required. With Qwiic and STEMMA QT connectivity and configurable I²C addressing, the module can be easily integrated into projects using Arduino, ESP32, Raspberry Pi, STM32, and RP2040 boards. It is well suited for IoT relay control, home automation, robotics, smart devices, and industrial automation projects where reliable two-channel load switching is required.
Features:
- Dual 10 A SPDT Relays: Use the NO, COM, and NC terminals to independently operate two suitable AC or DC loads.
- Simple I2C Control: Requires fewer MCU GPIO pins by using only SDA and SCL pins.
- Wide Compatibility: Compatible with Arduino, ESP32, Raspberry Pi, STM32, RP2040, and other 3.3V and 5V I2C systems.
- Simple Integration: Contains power/relay status LEDs, adjustable I2C addressing, and Qwiic/STEMMA QT connections.
- I2C address that can be selected at the bottom, with a default address of 0x20
