This tutorial will teach you what a bootloader is and why you would need to install or reinstall it. We will also go over the process of burning a bootloader by flashing a hex file to an Arduino microcontroller.
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.
