The SparkFun Qwiic Multiport adds additional ports to boards that have only one Qwiic port on their I2C bus. Once added, you can use it as a hub to add as many I2C devices to the bus as you need [1] ! You can also use the board as an alternative to a daisy chained configuration.

Required Materials

To follow along with this tutorial, you will need a microcontroller or single board computer with a Qwiic connector. You will also need a Qwiic cable and a way to power the board. You may not need everything though depending on what you have. Add it to your cart, read through the guide, and adjust the cart as necessary.

Besides having the Qwiic MultiPort in your cart, here are the parts if you decide to go with a microcontroller. You can easily swap out the microcontroller depending on your project's needs with MicroMod. Make sure to include the Qwiic-enabled device in your cart as well!
