Get our powerful Artemis based boards (Artemis Nano, BlackBoard Artemis, and BlackBoard Artemis ATP) blinking in less than 5 minutes using the SparkFun Artemis Arduino Core!

The SparkFun AzureWave Thing Plus is a Feather form-factor development board equipped with the AW-CU488. We'll highlight key features of the board and show you to get started with the development board. A few Arduino examples will be highlighted to connect to a WiFi router, calculate the Fast Fourier Transform (FFT) from an input microphone, output an analog signal to a speaker, and connect an Qwiic-enabled device.
