We've retired this version. V1.1 is available here.

The Qwiic Shield for Arduino connects the I²C bus (GND, 3.3V, SDA, and SCL) on any Arduino compatible board to the SparkFun Qwiic system. We've included conversion circuitry from 5V to 3.3V, so you don't have to worry about using the Qwiic system with 5V (or 3.3V) devices. Just plug the shield onto your Arduino or RedBoard, plug in a cable, and start playing with a variety of sensors and actuators. There are four connectors, all on the same I²C bus, so you can connect multiple devices.

Additionally, there is a large prototyping area with paired holes! Each pair has a horizontal trace connecting them that enables a DIP package or components to be wired together. A white silkscreen line indicates the location of each trace. This trace can be cut with a knife to break the connection if needed.

This product includes the R3 stackable headers to connect to the Arduino Uno, RedBoard, and many other Arduino compatible devices.

The Qwiic system enables fast and solderless connection between popular platforms and various sensors and actuators. You can read more about the Qwiic system here. We carry 200mm, 100mm, 50mm, and breadboard friendly Qwiic cables.

We do not plan to regularly produce SparkX products so get them while they’re hot!
