Recently got my hands on a MagTag kit from Adafruit. This is an ESP32-S2 board with built in wi-fi combined with an e-Ink display. The kit also includes a 420mAH battery that will last for weeks between charging due to this setup being low power friendly. We will see how long it last but so far ours has lasted for 5 days.
If you aren’t familiar with e-Ink, it is a black & white display that will show the screen even without power.
The MagTag kit also contains magnetic feet for attaching it to your fridge or other magnetic surface.
While Adafruit has a number of projects you can do I chose to do the MagTag Weather project. This project updates the weather once a day over wifi. It gives you todays weather as well as the week ahead but not hourly weather.
For this project you will need a data capable cable with USB C on one end to connect to your computer. You will also need some way of edit the files so the MagTag can connect to your wi-fi. For this I used a free Python editor called Thonny. Get al the details in Adafruit’s tutorial MagTag Weather.
The MagTag also has four buttons and four rgb leds on the front for use with other projects.
I can’t wait to try some of the other MagTag projects. We particularly like this one that combines several projects and allows you to select them using the buttons. MagTag Project Selector
