Waveshare ESP32-S3 4.3" Display Development Board 800x480 Display Board With Capacitive Touch Screen, Wi-Fi & Bluetooth

Description:

This is a low-cost, high-performance MCU development board designed by Waveshare. It supports 2.4GHz WiFi and BLE 5, integrates high-capacity Flash and PSRAM, and has a 4.3-inch wide capacitive touch LCD screen on board to smoothly run GUI interface programs such as LVGL. It combines a variety of peripheral interfaces (e.g., CAN, I2C, RS485, etc.) to quickly develop applications such as HMIs for ESP32-S3. With a wide range of functions and interfaces, it can meet power consumption requirements in Internet of Things (IoT), mobile devices, smart home, and other applications.
