LORDWORLD ESP32-S3 4.3inch LCD Development Board

SKU CH-HQ4H-TYYBS

ESP32-S3 development board with 4.3 inch IPS display, 160 degree viewing angle, dual-core 32-bit processor at 240MHz, 2.4GHz WiFi, BLE 5, CAN, RS485 and I2C interfaces

  • IPS panel gives 160° viewing angle for clear off-axis reading
  • 3 inch RGB LCD integrated directly on the board
  • Dual-core Xtensa LX7 processor runs up to 240 MHz for responsive edge tasks
  • 4 GHz WiFi and BLE 5 enable wireless connectivity out of the box
  • CAN, RS485 and I2C interfaces allow expansion with sensors and actuators

ESP32-S3 4.3inch LCD Development Board

This board integrates a 4.3 inch IPS display with RGB interface and a 160 degree viewing angle. It targets makers and engineers building IoT edge devices that need a built-in screen. The Xtensa 32-bit LX7 dual-core processor runs at up to 240 MHz. Wireless connectivity includes 2.4 GHz WiFi and BLE 5 support.

Thermals noise and power draw

The board operates without active cooling and draws modest power from a USB supply in typical development use. The dual-core processor scales frequency to match workload, keeping heat output low. No fan noise is present, making it suitable for quiet bench testing. Power consumption varies with display brightness and wireless activity.

Build quality and connectivity

The PCB exposes CAN, RS485, and I2C interfaces for industrial sensor expansion. Header pins allow straightforward wiring to external modules without soldering. The integrated LCD reduces cable clutter compared to separate display modules. Mounting holes enable secure installation in enclosures or prototype rigs.

Questions about this item

How do I connect the 4.3inch LCD to the ESP32-S3 board and which step is often missed?

The display uses an integrated RGB interface so no separate wiring is needed; the step often missed is enabling the RGB panel driver in the SDK configuration before flashing firmware.

What maintenance will the CAN and RS485 interfaces need over time?

Check termination resistors on the RS485 bus and verify CAN bus biasing resistors remain within spec; clean connector contacts if the board operates in dusty environments.

What thermal limit appears first when the dual-core processor runs at 240MHz continuously?

The on-board regulator reaches its temperature ceiling before the CPU throttles, so sustained 240MHz loads require added heatsinking or forced airflow.
