The Qwiic Connect System is a collection of I2C sensors, I/O boards, and cables designed to make prototyping faster, easier, and less prone to error. It was developed by SparkFun, who graciously made the standard available for others to use without royalties. The main features of the Qwiic Connect System are:
No soldering to connect Qwiic boards
Polarized connectors that prevent mistakes
Ability to daisy chain boards to quickly add functionality
