Qwiic/STEMMA QT Port Expander

The Qwiic/STEMMA QT Port Expander is a handy add-on board that allows multiple SparkFun Qwiic or Adafruit STEMMA QT breakout boards and sensors to be connected to a single port.

This version of the board allows for a single port to be expanded into 4, but its ports can also be used to provide additional power in systems with many sensors. Just note that multiple sensors of the same I2C address cannot be used with the board.

No additional code needs to be used with this board – it’s simply plug and play. A small LED is on board to indicate power, however this can be disabled by cutting the small solder-jumper trace on the back of the board.

Please Note: Cables and sensors are sold separately!
