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 including a few 5V and GND buses.

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!

Updates on version 1.1:

• Added mounting holes to make it easier to mount a Qwiic board to the shield
• Exposed buses are clearly visible
• New fancy black connectors: Ohhh! Ahhh!

• Four Qwiic connectors
• Protects and converts 3.3V I²C signals to 5V as needed
• Connector: SM04B-SRSS or equivalent
• All Arduino pins are broken out for easy soldering
• Large prototyping area
