ESP32-S3 Development Board with 4" Capacitive Touch LCD Display (480 x 480)

This ESP32-S3 development board has 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 (LE), making it ideal for smart control panels, home gateways, and industrial control systems. A 16MB Flash and 8MB PSRAM provide ample memory to work with different projects.

The board has a 4" capacitive touch display with a 480 x 480 resolution, 160° wide viewing angle and 65K colours providing smooth and vibrant graphics from most points of viewing, capable of running sophisticated GUI programs like LVGL. The 5-point touch interface, controlled via I2C, has advanced touch interactions, making it very responsive for easy control.

Powered by the Xtensa 32-bit LX7 dual-core processor with a clock speed of up to 240MHz, this board can handle big tasks efficiently. Additionally, it comes with multiple peripheral interfaces, including CAN, RS485, I2C, and an SD card slot, along with a full-speed USB port, making it a versatile option for various projects.
