- Foldable and portable cat bagSparkFun Qwiic Shield for Arduino Nano

• SparkFun Qwiic Shield for Arduino Nano
• Offers Logic Shifting Circuit and IOREF Jumper
• Arduino Nano and Qwiic compatible
• Features I2C Jumper
• Provides 3.3V and GND Buses

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 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.
