ESP32-S3 4.3-inch Capacitive Touch Display Development Board 800×480 with Case

The ESP32-S3 4.3inch Capacitive Touch Display Development Board combines high performance and user-friendliness in a compact design with a robust case. Featuring a 4.3-inch capacitive touch display with a resolution of 800x480 pixels, this board offers clear and responsive display for demanding applications. The powerful Xtensa 32-bit LX7 dual-core processor with up to 240 MHz clock speed and integrated memory (8 MB PSRAM and 8 MB Flash) allows for smooth execution of complex user interfaces, for example, based on the LVGL graphics library. WiFi and Bluetooth 5 enable wireless connections, while interfaces like CAN, RS485, and I2C provide versatile communication options. Isolated inputs and outputs enhance safety in industrial environments, and the USB-C port ensures easy programming and power supply. This board is optimally suited for IoT applications, smart home controls, mobile devices, and industrial monitoring instruments.
