Sparkfun Qwiic

The SparkFun Qwiic Connect System from Sparkfun 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 (“chips”) to communicate with one or more “master” chips with a mere two wires. We've adapted that technology to unlock the following benefits:

  1. No soldering between Qwiic breakout boards
  2. Polarized connectors to prevent mistakes
  3. Daisy chain capabilities to quickly add functionality
