Wave ESP32-S3 2.8" Touch IPS Display

The Waveshare ESP32-S3 2.8" Touch IPS Display is a powerful development board that integrates wireless connectivity, rich peripherals, and a vibrant capacitive touchscreen. Featuring an Xtensa LX7 dual-core processor running up to 240MHz, with 16MB Flash and 8MB PSRAM, it delivers the performance needed for GUI frameworks like LVGL, interactive HMI projects, and smart IoT applications.



The 2.8" TFT LCD with capacitive 5-point touch provides smooth user interaction, while onboard Wi-Fi, Bluetooth 5 (BLE), USB Type-C, a 6-axis motion sensor, real-time clock, audio decoder, TF card slot, speaker, and battery management system make it a versatile all-in-one platform. With support for flexible power modes and expansion via GPIO, UART, and I²C, this ESP32-S3 development board is an excellent choice for building intelligent, connected, and interactive devices.
