Could you provide correct GPIO pin configuration for CS, DC, RST, MOSI, and SCLK on this board?

Hi,

Here is the GPIO pin configuration for the T-Dongle-S3 with the ST7735 display (based on the manufacturer's datasheet and schematics):

CS → GPIO 10

DC → GPIO 11

RST → GPIO 12

MOSI → GPIO 13

SCLK → GPIO 14

This is normally the correct default mapping for this board. If you are using TFT_eSPI or LVGL, you can configure it directly in the User_Setup.h file.

Try running a simple display example to verify, and let us know if it works.
