7Semi SPDT Single Channel I2C Qwiic 5V DC Input Relay Module 230V AC 10A Load
The 7Semi SPDT Single Channel I2C Qwiic 5V DC Input Relay Module is a convenient solution for controlling high-power electrical devices from a microcontroller using a simple I2C interface. With just two I2C wires, you can switch lights, pumps, appliances, and other electrical equipment ON or OFF without requiring a large number of GPIO pins.
The module supports 3.3V and 5V operation, making it compatible with popular development platforms such as Arduino, ESP32, Raspberry Pi, and other microcontroller boards. Its Qwiic and STEMMA QT connectors allow quick plug-and-play connections without soldering, while the standard header pins provide additional flexibility for custom wiring.
With a single SPDT relay supporting up to 230V AC and 10A loads, this I2C relay module is well suited for home automation, industrial control, DIY electronics, pump switching, lighting control, and embedded automation projects.
Features:
- MCU-Friendly I2C Control: Compatible with Arduino, ESP32, Raspberry Pi, STM32, and RP2040; uses SDA and SCL.
- Flexible Connectivity: 5V input, 3.3V/200 mA auxiliary output, customizable I2C addressing, Qwiic/STEMMA QT support.
- 10A SPDT Switching: Features four mounting holes, NO, COM, and NC terminals, status LEDs, and a small 53 × 26 mm design.
