M5Stack CoreS3 2.0" specifications
The M5Stack CoreS3 2.0" is a 2.0" 320×240 display board by M5Stack, built around the ESP32-S3 (ESP32-S3 module) running at 240 MHz. The panel uses a ILI9342C (SPI) controller over SPI, with FT6336U (I2C, reset via an AW9523B IO expander) touch input. Memory: 16 MB flash, 8 MB PSRAM (QSPI); wireless: Wi-Fi and Bluetooth. In LCD Ultra Pro you can design its UI visually at the exact resolution; a ready-made display driver for the Arduino export is not available yet, so the export contains the LVGL UI code for your own project.

Pick this board in the editor and the canvas matches its exact resolution and shape. Build the interface with widgets, add events without code, try it in Live Preview, then export it as LVGL UI code. See the documentation for the workflow.
Frequently asked questions
What is the resolution of the M5Stack CoreS3 2.0"?
320×240 pixels on a 2.0" screen, driven at 16-bit colour depth.
Which display controller and interface does it use?
ILI9342C (SPI) over SPI.
Does the M5Stack CoreS3 2.0" have a touchscreen?
Yes — FT6336U (I2C, reset via an AW9523B IO expander).
Which ESP32 chip and how much memory does it have?
ESP32-S3 (ESP32-S3) at 240 MHz, 16 MB flash, 8 MB PSRAM (QSPI).
Which GPIOs are free for my own sensors or relays?
6 GPIOs are free: GPIO 1, GPIO 2, GPIO 8, GPIO 9, GPIO 17, GPIO 18.
Can I use LVGL on the M5Stack CoreS3 2.0"?
Yes, with your own display driver setup. In LCD Ultra Pro you can design the UI at the board’s exact resolution and export the LVGL 8.4 UI and event code; a ready-made display driver for this board is not included yet, so you call ui_init() from your own LVGL project.
