Introduction

The SparkFun Qwiic Shield for Teensy and SparkFun Qwiic Shield for Teensy Extended provide an easy-to-assemble way to add the SparkFun Qwiic ecosystem to Teensy development boards. Both of these shields connect the I2C bus (GND, 3.3V, SDA, and SCL) on your Teensy to four SparkFun Qwiic connectors. The Qwiic ecosystem allows for easy daisy chaining so, as long as your devices are on different addresses, you can connect as many Qwiic devices as you'd like.
