EEPROM is a great way to add extra memory to your microcontroller project. Wait 'til you see how easy it is to use!

Running out of memory? Don't forget to check out the Qwiic EEPROM!

Have a bunch of sensors with the same I2C address? Put them on the Qwiic MUX (TCA9548A) to get them all talking on the same bus!

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! You can also use the board as an alternative to a daisy chained configuration.

Need to add more analog inputs for your project? Check out the Qwiic 12-bit ADC.
