Waveshare ESP32-S3-Touch-LCD-4B Smart 86 Box Touch Display Dev Board

Description

Waveshare ESP32-S3-Touch-LCD-4B Smart 86 Box Touch Display Dev Board is a high-integration development board designed for smart wall panels, home gateways, industrial HMI, and interactive control terminals. It is built around the ESP32-S3-WROOM-1-N16R8 with 16MB Flash and 8MB PSRAM, and integrates a 4 inch 480 480 capacitive touch LCD that can smoothly run LVGL interfaces. The board also includes ST7701 display driver, GT911 5-point touch controller, QMI8658 6-axis IMU, PCF85063 RTC, AXP2101 power management, ES7210, ES8311, microphone support, TF card support, battery charging, and multiple expansion interfaces for smart central control projects.

Features

• ESP32-S3 platform with dual-core Xtensa LX7 architecture and clock speed up to 240MHz.
• 4 inch RGB LCD with 480 480 resolution for rich GUI and smart panel applications.
• 5-point capacitive touch using the GT911 touch controller over I2C.
• Wireless connectivity through 2.4GHz Wi-Fi and Bluetooth 5 LE.
• LVGL-ready hardware for embedded GUI and HMI development.
• Audio subsystem with ES7210 echo cancellation and ES8311 codec support.
• Battery-capable design with PH2.0 lithium battery connector and charge/discharge management.
• Expanded peripheral support with GPIO, UART, and external module connections for control panel integration.
