Waveshare ESP32-S3 4.3inch 800×480 Touch LCD Development Board without Case

Develop embedded projects with the Waveshare ESP32-S3 4.3-Inch Touch LCD Development Board. Featuring a dual-core processor, a high-resolution capacitive touchscreen and versatile communication interfaces, this development board is suitable for interactive control panels, industrial monitoring systems and custom human-machine interface (HMI) applications. Supplied without a case, it offers a flexible platform for hardware integration and GUI development.

Key Features

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

2. Wireless Connectivity: Supports 2.4 GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 Low Energy (BLE). An onboard antenna provides convenient wireless connectivity for compatible projects.

3. Memory and Storage: Includes 512 KB SRAM, 384 B ROM, 16 MB stacked Flash and 8 MB PSRAM to support application code, data storage and graphical operations.

4. 4.3-Inch Capacitive Touchscreen: The integrated LCD features an 800 × 480 resolution and supports 65K colours, making it suitable for interactive displays, dashboards and custom control interfaces.

5. Five-Point Multi-Touch: The capacitive touchscreen supports up to five touch points, communicates through I²C and provides interrupt support for responsive user interaction.

6. Wide-Range Power Input: An onboard voltage regulator supports a 7–36 V power supply, offering flexibility for different embedded and industrial installations.

7. Real-Time Clock (RTC): The onboard RTC chip and rechargeable battery help preserve timekeeping when the main power supply is disconnected.

8. Versatile Interfaces: Includes CAN, RS485 and I²C interfaces, a Micro SD card slot, a GH1.25 2-pin battery connector and isolated digital I/O for connecting compatible peripherals and external equipment.

9. Isolated Digital Inputs: Bidirectional optocoupler isolation supports both passive and active switch inputs. Active inputs support positive and negative voltage configurations.

10. Isolated Digital Outputs: Optocoupler-isolated outputs provide enhanced drive capability, with a maximum sink current of up to 450 mA, according to the specified operating conditions.

11. Convenient Status Indicators: External LED indicators make it easier to check power and battery-charging status.

12. Flexible Power Management: Supports configurable clock settings and separate module power control, enabling low-power operating modes for different application requirements.

13. GUI Development Support: Suitable for HMI projects and graphical interface development using LVGL, making it useful for prototyping interactive embedded devices.
