Mellow's FLY-HALO WiFi IPS 1.28 inch Circular Smart Touch Screen is designed for 3D printers and is compatible with Capacitive Touch and Klipper. The main controller is an ESP32-S3R8, equipped with 8MB of PSRAM and 16MB of Flash memory for powerful performance. Its high-resolution IPS screen has a wide viewing angle and delicate colors for optimal images. The 6 pages of the screen are controlled by swiping left and right or up and down. The home page displays standby, printing, shutdown, and error states, while the Filament Detection page detects filament runout, blockages, and length. An additional shell print file also allows you to use the device as a desktop decoration. The device is currently only compatible with Klipper, but future updates will include RRF compatibility.
