So you may have heard of the Adafruit MagTag and you want to get started with building a project using CircuitPython. As the name implies, the MagTag was designed to be a low-powered "tag" that you could attach to your refrigerator with magnetic feet. The MagTag library makes it really easy to get started with creating a new project, using this board, but it also supports a variety of other hardware pieces to make creating projects to display on the ePaper display very easy.

This library is built on top of the PortalBase library, which in turn is built on top of displayio which is included as part of CircuitPython. It also makes use of the ESP32-S2 wifi module, along with some lower-level dependencies, to communicate with server over the internet.

One of the latest features of CircuitPython, which is made easy with this library, is the ability to put the MagTag into deep sleep, which is a very low power mode. We will go over that plus more in this guide.
