Qwiic Connect System

SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields, and cables that make prototyping faster and less prone to error. The Qwiic Connect System uses the Inter-integrated Circuit (I2C) Protocol. I2C protocol is intended to allow multiple "slave" digital integrated circuits to communicate with one or more "master" chips with only two wires.
