Wave ESP32-S3 Round 2.8" Capacitive Touch Display

The ESP32-S3-Touch-LCD-2.8C is a powerful microcontroller development board featuring a 2.8-inch capacitive touch display with a 480×480 resolution. Powered by the high-performance Xtensa 32-bit LX7 dual-core processor running at up to 240MHz, it supports 2.4GHz Wi-Fi and Bluetooth 5 (BLE) for wireless connectivity.



With 16MB Flash, 8MB PSRAM, and multiple peripheral interfaces, it provides an ideal platform for HMI applications and ESP32-S3-based projects. The board also integrates a QMI8658 6-axis sensor, RTC clock, TF card slot, and a battery management module, offering a comprehensive solution for GUI-driven applications.
