Waveshare ESP32-S3 IPS LCD 4.3" 800×480 with Case – 2× Digital IO

The ESP32-S3-Touch-LCD-4.3B is a microcontroller development board featuring 2.4GHz Wi-Fi and BLE 5 support, and integrates high-capacity Flash and PSRAM. The onboard 4.3-inch capacitive touch screen can smoothly run GUI programs such as LVGL. Combined with various peripheral interfaces, it is suitable for rapid development of HMI and other ESP32-S3 applications.
