The panel's 30-pin FPC is pin-for-pin compatible with the board's display connector — plug the flex, power up, and the circular UI is on screen.

Around it are the parts a finished device needs — MIPI-CSI camera input, an ES8389 audio codec with two microphones and stereo Class-D amplifiers, a MicroSD slot, USB 2.0 High-Speed, a 3-axis accelerometer, and AXP2101 lithium-battery charging. Its AI instruction extensions and FPU run wake-word and vision models on-device through ESP-SR and ESP-DL; the language model stays in the cloud over Wi-Fi 6.
