Sunton (CYD) ESP32-2424S012C 1.28" round specifications
The Sunton (CYD) ESP32-2424S012C 1.28" round is a 1.28" 240×240 display board by Sunton / CYD, built around the ESP32-C3 (ESP32-C3-MINI-1U module) running at 160 MHz. The panel uses a GC9A01 (SPI) controller over SPI, with CST816D (I2C, addr: 0x15) touch input. Memory: 4 MB flash, no PSRAM; 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.

Frequently asked questions
What is the resolution of the Sunton (CYD) ESP32-2424S012C 1.28" round?
240×240 pixels on a 1.28" screen, driven at 16-bit colour depth.
Which display controller and interface does it use?
GC9A01 (SPI) over SPI.
Does the Sunton (CYD) ESP32-2424S012C 1.28" round have a touchscreen?
Yes — CST816D (I2C, addr: 0x15).
Which ESP32 chip and how much memory does it have?
ESP32-C3 (ESP32-C3-MINI-1U) at 160 MHz, 4 MB flash, no PSRAM.
Which GPIOs are free for my own sensors or relays?
None — every GPIO is used by the display, touch or on-board peripherals.
Can I use LVGL on the Sunton (CYD) ESP32-2424S012C 1.28" round?
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.
