Guition ESP32-S3 Smart Panel 4.0" (4848S040) specifications
The Guition ESP32-S3 Smart Panel 4.0" (4848S040) is a 4.0" 480×480 display board by Guition, built around the ESP32-S3 (ESP32-S3-DevKitC-1 modul, OPI PSRAM module) running at 240 MHz. The panel uses a ST7701S (RGB Parallel + 3-wire SPI init) controller over RGB565 Parallel (DPI) + SPI init sequence, with GT911 (I2C) touch input. Memory: 16 MB flash, 8 MB PSRAM; wireless: Wi-Fi and Bluetooth. LCD Ultra Pro supports it with a ready-made LVGL 8.4 display driver, so you can design its UI visually and export a complete Arduino project.
