Product Pin Diagram

T-Display-S3 is a ESP32-S3 development board.

It is equipped with a color 1.9" LCD screen and two programmable buttons.

Communication using I8080 interface. Retains the same layout design as T-Display.

You can directly use ESP32S3 for USB communication or programming.

• This version was shipped with welded pins
• For more product information, please refer to Github : github.com/Xinyuan-LilyGO/T-Display-S3

NOTE:

1. The program can be written normally, but there is still no display after writing.

• There are factory test files in the firmware folder, which can be flashed into the board to check whether the board is normal.

If there is still no display, then it can be judged that there is a problem with the board or the screen.

• Delete the ( TFT_eSPI ) in the libraries, and replace the ( TFT_eSPI ) in the folder of the main page to the libraries directory
• When opening the Arduino IDE, it prompts whether to upgrade the library, please choose not to upgrade, otherwise it will overwrite the configuration of the ( TFT_eSPI ) display

2. The factory sample program includes steps for connecting to WiFI

Due to the need to increase the power of the chip when searching for WiFi signals, it is normal for the chip to generate heat.

When you connect to WiFi or after the program runs, the search will stop and the normal operating temperature will be restored.
