It won't work as a badge out of the box, but if you know how to program an ESP32, it's easy to get it to use the demo libraries to load a JPG. It also has a touchscreen and 3 physical buttons for basic interactivity. It's $85, so it's pricy for being used just as a badge, but it's a cool gadget that I use for a desktop display.
