The Sparkfun Qwiic GPIO is an I²C device based around the TCA9534 I/O Expander IC from Texas Instruments. The board adds an additional eight IO pins which you can read and write just like any other digital pin on your controller. The details of the I²C interface have been taken care of in an Arduino library so you can call functions similar to Arduino's pinMode and digitalWrite, allowing you to focus on your creation!
