The ESP32-P4X AI Box drives a 3.4-inch round TFT at 800 × 800 over MIPI-DSI, with capacitive touch on I²C. That is more than two and a half times the pixels of a 2.8-inch 480 × 480 round screen, enough for fine dial markings, animated faces, live camera previews and readable text inside a circular frame.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe display flex connects straight to the board’s display connector.

A full 800 × 800 frame takes only about 1.3 MB in RGB565 (1.9 MB in RGB888), so double buffering fits comfortably in PSRAM. Camera input, a two-mic audio codec, stereo amplifiers, a MicroSD slot, USB 2.0 High-Speed and lithium-battery charging are all on the same board, so you can go from prototype to a working device without adding modules.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e \u003c\/p\u003e\n\u003ch2 dir=\"ltr\"\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/h2\u003e\n\u003ch3\u003e\u003cstrong\u003e3.4-Inch Round Display\u003c\/strong\u003e\u003c\/h3\u003e\n\u003ctable style=\"width: 100%;
