Five buttons and a screen.

The ESP32-S3 on the back drives the screen, reads its buttons and runs the code you load on it over USB-C. Here are three things it can show, drawn at the screen's own 320 × 240.

The badge's front square on: the screen in its clear case, the five buttons under it, PWR, RST and BOOT on the right edge.
