The Badge Turns a Round AMOLED Module Into a Wearable Trackpad, Recorder and Fidget Toy
The Badge is MIT-licensed ESP32-S3 firmware for the Waveshare ESP32-S3-Touch-AMOLED-1.75C — a 466×466 round AMOLED display — adding a BLE trackpad and air mouse, clock and timer, games, a liquid simulation and up to 52 minutes of WAV recording. It also builds and runs on a PC.
