About this item

The SparkFun BOB-18012 Qwiic MultiPort is a versatile I2C expansion board designed to simplify the connection of multiple Qwiic devices to a single microcontroller. This breakout board provides four Qwiic-compatible ports, allowing you to easily connect several sensors, displays, or other I2C modules without worrying about complex wiring or soldering. With the Qwiic system’s plug-and-play design, the MultiPort expands the number of available I2C connectors, enabling quick prototyping and flexible project development. Each port is wired in parallel to the I2C bus, maintaining signal integrity and ensuring reliable communication between all connected devices. The compact and breadboard-friendly form factor makes the Qwiic MultiPort ideal for space-constrained projects and prototyping setups. It supports 3.3V logic levels, matching common microcontroller voltage requirements such as those found on SparkFun RedBoard, Arduino, and Raspberry Pi. This board is particularly useful in IoT, robotics, and embedded systems projects where multiple sensors or modules need to share a single I2C bus, reducing cable clutter and improving system organization. The Qwiic MultiPort saves time and increases reliability in your designs by providing a clean, efficient way to expand your sensor or peripheral connections.
