The 7Semi Qwiic – Grove I2C Hub is a compact and convenient expansion board designed to simplify the connection of multiple I2C devices to a single microcontroller or development platform. By providing one Qwiic input connector and multiple Grove-compatible I2C output ports, the hub enables rapid prototyping and modular system development without the need for complex wiring or custom PCB designs. It is an ideal accessory for sensor networks, IoT devices, robotics projects, educational kits, and embedded development platforms.
The hub operates as a passive I2C signal distribution board, routing the SDA, SCL, power, and ground connections from a single host controller to multiple connected peripherals. This allows users to connect several I2C sensors, displays, environmental monitoring modules, motion sensors, and communication devices while maintaining a clean and organized wiring layout. The standardized connector ecosystem reduces development time and helps eliminate wiring errors during prototyping.
Compatible with Arduino, ESP32, STM32, Raspberry Pi, RP2040, micro:bit, and other I2C-capable systems, the 7Semi Qwiic – Grove I2C Hub is perfect for rapidly expanding sensor connectivity in embedded applications. Whether you're building a weather station, smart home controller, industrial monitoring system, robotics platform, or educational electronics project, this hub provides a reliable and user-friendly method of distributing I2C communication signals. The board is designed for reliable operation from -40°C to +80°C
