It has the functions of touch screen interaction and voice interaction. The development board has the following characteristics: * Onboard ESP32-S3-WROOM-1 module, with built-in 16 MB Flash + 8/16 MB PSRAM * Onboard audio codec + audio amplifier * Onboard dual microphone pickup * USB type-C interface download and debugging * It can be used with different screen sub boards, and supports `RGB`, `8080`, `SPI`, `I2C` interface screens, as below: | Board Name | Screen Size (inch) | Resolution | LCD Driver IC (Interface) | Touch Driver IC | Schematic | Support | | -------------------------- | ------------------ | ---------- | ------------------------- | --------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------- | | ESP32-S3-LCD-EV-Board-SUB1 | 0.9 | 128 x 64 | SSD1315 (I2C) | * | [link](https://docs.espressif.com/projects/esp-dev-kits/zh_CN/latest/_static/esp32-s3-lcd-ev-board/schematics/SCH_ESP32-S3-LCD-Ev-Board-SUB1_V1.0_20220617.pdf) | Not yet | | | 2.4 | 320 x 240 | ST7789V (SPI) | XTP2046 | | Not yet | | ESP32-S3-LCD-EV-Board-SUB2 | 3.5 | 480 x 320 | ST7796S (8080) | GT911 | [link](https://docs.espressif.com/projects/esp-dev-kits/zh_CN/latest/_static/esp32-s3-lcd-ev-board/schematics/SCH_ESP32-S3-LCD-EV-Board-SUB2_V1.2_20230509.pdf) | Not yet | | | 3.95 | 480 x 480 | GC9503CV (RGB) | FT5x06 | | Yes | | ESP32-S3-LCD-EV-Board-SUB3 | 4.3 | 800 x 480 | ST7262E43 (RGB) | GT1151 | [link](https://docs.espressif.com/projects/esp-dev-kits/zh_CN/latest/_static/esp32-s3-lcd-ev-board/schematics/SCH_ESP32-S3-LCD-EV-Board-SUB3_V1.1_20230315.pdf) | Yes | Here are some useful configurations in menuconfig that can be customed by user: * `BSP_LCD_RGB_BUFFER_NUMS`: Configure the number of frame buffers. The anti-tearing function can be activated only when set to a value greater than one. * `BSP_LCD_RGB_REFRESH_MODE`: Choose the refresh mode for the RGB LCD. * `BSP_LCD_RGB_REFRESH_AUTO`: Use the most common method to refresh the LCD. * `BSP_LCD_RGB_REFRESH_MANUALLY`: Refresh the LCD within a dedicated task. This can help manage PSRAM bandwidth. * `BSP_LCD_RGB_BOUNCE_BUFFER_MODE`: Enabling bounce buffer mode can lead to a higher PCLK frequency at the expense of increased CPU consumption. **This mode is particularly useful when dealing with [screen drift](https://docs.espressif.com/projects/esp-faq/en/latest/software-framework/peripherals/lcd.html#why-do-i-get-drift-overall-drift-of-the-display-when-esp32-s3-is-driving-an-rgb-lcd-screen), especially in scenarios involving Wi-Fi usage or writing to Flash memory.** This feature should be used in conjunction with `ESP32S3_DATA_CACHE_LINE_64B` configuration. For more detailed information, refer to the [documentation](https://docs.espressif.com/projects/esp-idf/en/latest/esp32s3/api-reference/peripherals/lcd.html#bounce-buffer-with-single-psram-frame-buffer). * `BSP_DISPLAY_LVGL_BUF_CAPS`: Select the memory type for the LVGL buffer. Internal memory offers better performance. * `BSP_DISPLAY_LVGL_BUF_HEIGHT`: Set the height of the LVGL buffer, with its width aligning with the LCD's width. The default value is 100, decreasing it can lower memory consumption. * `BSP_DISPLAY_LVGL_AVOID_TEAR`: Avoid tearing effect by using multiple buffers. This requires setting `BSP_LCD_RGB_BUFFER_NUMS` to a value greater than 1. * `BSP_DISPLAY_LVGL_MODE`: * `BSP_DISPLAY_LVGL_FULL_REFRESH`: Use LVGL full-refresh mode. Set `BSP_LCD_RGB_BUFFER_NUMS` to `3` will get higher FPS when enable `BSP_DISPLAY_LVGL_ROTATION_NONE`. * `BSP_DISPLAY_LVGL_DIRECT_MODE`: Use LVGL's direct mode. * `BSP_DISPLAY_LVGL_ROTATION`: Rotate the screen clockwise. This requires setting `BSP_LCD_RGB_BUFFER_NUMS` to `3`. **The rotation is software-based and will substantially reduce FPS if enabled.** * `BSP_DISPLAY_LVGL_ROTATION_NONE`: No rotation. * `BSP_DISPLAY_LVGL_ROTATION_90`: 90-degree rotation. * `BSP_DISPLAY_LVGL_ROTATION_180`: 180-degree rotation. * `BSP_DISPLAY_LVGL_ROTATION_270`: 270-degree rotation. Based on the above configurations, there are three different anti-tearing modes can be used: * RGB double-buffer + LVGL full-refresh mode: * Set `BSP_LCD_RGB_BUFFER_NUMS` to `2` * Enable `BSP_DISPLAY_LVGL_AVOID_TEAR` and `BSP_DISPLAY_LVGL_FULL_REFRESH` * RGB double-buffer + LVGL direct-mode: * Set `BSP_LCD_RGB_BUFFER_NUMS` to `2` * Enable `BSP_DISPLAY_LVGL_AVOID_TEAR` and `BSP_DISPLAY_LVGL_DIRECT_MODE` * RGB triple-buffer + LVGL full-refresh mode: * Set `BSP_LCD_RGB_BUFFER_NUMS` to `3` * Enable `BSP_DISPLAY_LVGL_AVOID_TEAR` and `BSP_DISPLAY_LVGL_FULL_REFRESH`
