ESP32-S3 3.5-inch touch display: getting started

Identify the display board

This guide is associated with our ESP32-S3 3.5-inch capacitive touch display product. Compare the product model, PCB marking and hardware revision before using a demonstration project.

First connection

Use a USB data cable and follow the board power instructions. Identify its USB interface and serial port. Keep peripheral wiring disconnected during initial setup.

Development environment

For Arduino, follow the ESP32 setup guide. For ESP-IDF, use the version and dependencies specified by the example project.

Select a display example

Use an example for the exact hardware revision. Confirm the display and touch controllers, interfaces, pin assignments and memory configuration against the manufacturer files.

A generic serial example checks microcontroller communication; it is not a screen or touch demonstration.

Build and upload

Follow the project dependency and upload instructions. Record toolchain and library versions so the setup can be reproduced.

Verify the display

1. Read the startup log after reset.
2. Check screen updates using the supplied demonstration.
3. Check touch input using the project test screen.
4. Record any orientation or coordinate issues before changing configuration.
