Waveshare ESP32-S3 4.3inch 800×480 Touch LCD Development Board With Case

Build interactive embedded projects and smart control systems with the Waveshare ESP32-S3 4.3-Inch Touch LCD Development Board. Powered by a dual-core Xtensa 32-bit LX7 processor running at up to 240MHz, this versatile development platform combines a high-resolution capacitive touchscreen, wireless connectivity and a range of industrial communication interfaces.

Featuring a 4.3-inch 800×480 LCD with 65K colours, 5-point capacitive touch and built-in Wi-Fi and Bluetooth 5 LE, it is ideal for developing graphical user interfaces, industrial control panels, smart home applications and HMI systems using LVGL.

The board also integrates CAN, RS485, I2C, Micro SD storage and optocoupler-isolated digital inputs and outputs, providing flexible connectivity for automation and embedded control projects.

Key Features

1. Powerful ESP32-S3 Dual-Core Processor – Built around the Xtensa 32-bit LX7 dual-core processor with a clock frequency of up to 240MHz, delivering efficient processing for embedded applications and graphical interfaces.

2. 4.3-Inch High-Resolution Touchscreen – Integrated 800×480 LCD with 65K colours provides a clear display for interactive menus, dashboards, monitoring screens and control interfaces.

3. 5-Point Capacitive Touch – Supports multi-touch operation with up to five simultaneous touch points, I2C communication and interrupt functionality for responsive user interaction.

4. Wi-Fi and Bluetooth 5 LE Connectivity – Built-in 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 Low Energy support wireless communication with compatible devices and networks. An onboard antenna is included.

5. Integrated Memory Resources – Features 512KB SRAM, 384KB ROM, 16MB Flash and 8MB PSRAM to support application code, graphics and data processing.

6. Wide-Voltage Power Input – Onboard voltage regulator supports a 7–36V DC power supply, making the board suitable for a variety of embedded and industrial environments.

7. Real-Time Clock (RTC) – Integrated RTC chip with a rechargeable backup battery helps retain time information when the main power supply is disconnected.

8. Industrial Communication Interfaces – Equipped with CAN, RS485 and I2C interfaces, providing connectivity options for industrial equipment, sensors and automation systems.

9. Optocoupler-Isolated Digital Inputs – Supports passive and active switch inputs. Active input supports both positive and negative voltage configurations, helping provide electrical isolation for connected control signals.

10. Optocoupler-Isolated Digital Outputs – Isolated output design provides enhanced compatibility with external control circuits, with a maximum sink current of up to 450mA, according to the manufacturer's specification.

11. Micro SD Card Support – Integrated Micro SD card slot allows additional storage for data logging, configuration files and application resources.

12. Low-Power Management – Supports flexible clock configuration, independent module power management and different low-power operating modes for energy-conscious applications.

13. External LED Indicators – Convenient LED indicators allow users to check power and battery charging status.

14. Protective Case Included – Supplied with a protective enclosure for a more convenient and organised development setup.
