Product Introduction

ESP32-S3-Touch-LCD-4.3 is a microcontroller development board with 2.4GHz WiFi and BLE 5 support, and integrates high-capacity Flash and PSRAM. Onboard 4.3-inch capacitive touch screen can smoothly run GUI programs such as LVGL. Combined with various peripheral interfaces, suitable for the quick development of the HMI and other ESP32-S3 applications.

Features

• Equipped with Xtensa 32-bit LX7 dual-core processor, up to 240MHz main frequency.

• Supports 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 (LE), with an onboard antenna.

• Built-in 512KB of SRAM and 384KB ROM, with onboard 8MB PSRAM and 8MB Flash.

• Onboard 4.3inch capacitive touch display, 800×480 resolution, 65K color.

• Supports capacitive touch control via I2C interface, 5-point touch with interrupt support.

• Onboard CAN, RS485, I2C interface, and TF card slot, integrate full-speed USB port.

• Supports flexible clock, module power supply independent setting, and other controls to realize low power consumption in different scenarios

Environment Setting

The software framework for ESP32 series development boards is completed, and you can use CircuitPython, MicroPython, and C/C++ (Arduino, ESP-IDF) for rapid prototyping of product development. Here's a brief introduction to these three development approaches:

CircuitPython is a programming language designed to simplify coding tests and learning on low-cost microcontroller boards. It is an open-source derivative of the MicroPython programming language, primarily aimed at students and beginners. CircuitPython development and maintenance are supported by Adafruit Industries.

• You can refer to development documentation for CircuitPython-related applications development.

• The GitHub library for CircuitPython allows for recompilation for custom development.

MicroPython is an efficient implementation of the Python 3 programming language. It includes a small subset of the Python standard library and has been optimized to run on microcontrollers and resource-constrained environments.

• You can refer to development documentation for MicroPython-related application development.

• The GitHub library for MicroPython allows for recompilation for custom development.

The official libraries and support from Espressif Systems for C/C++ development make it convenient for rapid installation.

• Users can select Arduino

• Visual Studio Code (ESP-IDF) as their Integrated Development Environment (IDE).

The environment is set up under Windows 10, users can choose to use Arduino or Visual Studio Code (ESP-IDF) as IDE for development, Mac/Linux OS users please refer to the official instructions.

Arduino

• Download and install Arduino IDE.

• Install ESP32 on the Arduino IDE as shown below, and you can refer to this link.

• Fill in the following link in the Additional Boards Manager URLs section of the Settings screen under File -> Preferences and save.
