SparkFun Qwiic Shield for Arduino Nano

The SparkFun Qwiic Shield for Arduino Nano provides you with a quick and easy way to enter into SparkFun's Qwiic ecosystem with your Arduino Nano board. The Qwiic shield connects the I2C bus (GND, 3.3V, SDA and SCL) on your Arduino Nano to four SparkFun Qwiic connectors (two horizontally and two vertically mounted). The Qwiic connect system allows for easy daisy chaining so long as your devices are on different addresses, you can connect as many Qwiic devices as you would like.

The Qwiic Shield for Arduino Nano has a configurable logic shifting circuit depending on the voltage your Arduino Nano runs at. There is a jumper on the shield to set the IOREF voltage for the logic shifting circuit. The jumper defaults to 3.3V but you can easily switch the jumper to 5V with a bit of solder.

All that is needed to get started using the Qwiic Shield for Arduino Nano is to solder your chosen headers to the shield and, if necessary, to your Arduino Nano. Take care to match the markings on the Qwiic Shield to the appropriate pins on your Nano to avoid shorting anything out and possibly damaging your boards.


The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.

SparkFun Qwiic Shield for Arduino Nano Product Help and Resources

Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

1 Soldering

Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.
