Displays

The Replay 2026 Badge has two displays: a monochrome 128x64 OLED and a red 8x8 LED matrix. The OLED is great for text, UI, and simple graphics, while the LED matrix is perfect for bold, low-res images and animations.

The badge has an accelerometer that keeps track of orientation. When it's hanging around your neck in a normal position, the OLED displays your name. When you turn it up to face you, it displays an interactive menu.
