A QWIIC 4 IN 1 expands a single I²C port into four, enabling easy connection of multiple Qwiic devices without soldering.

Pin Configuration

  • GND : Common ground reference for power and signals
  • SCL : I²C Serial Clock line used for communication timing
  • SDA : I²C Serial Data line used for data transfer
  • 3V3 : Provides regulated 3.3V power to connected Qwiic devices

Key Features

  • Four plug-and-play I²C ports
  • 3.3V compatible
  • Compact and easy integration

Applications

  • Multi-sensor setups
  • Rapid prototyping
  • IoT and embedded projects
  • Ensure all devices use 3.3V logic
  • Avoid I²C address conflicts
  • Keep cables short for stable communication
