These did a job for me (->TFT control; not sound/SD) PIN_NUM_MISO 0 // SPI MISO PIN_NUM_MOSI 23 // SPI MOSI / SDA PIN_NUM_CLK 18 // SPI CLOCK pin PIN_NUM_CS 05 // Display CS pin PIN_NUM_DC 16 // Display command/data pin / RS PIN_NUM_TCS 0 // Touch screen CS pin PIN_NUM_RST 17 // GPIO used for RESET control PIN_NUM_BCKL 0 // GPIO used for backlight control

HI @TridentTD , As you might have found there is no PIN to control the backlight mentioned. Possibly there is a way to switch the backlight via writing/setting certain control registers... frankly I have no experience on which common drivers (ILI9341) support this (in which way)... The reason I put the pin about backlight in the example above: it's there as a default PIN definition in a few libs like ESP32_TFT_library.

Stumbling upon this years later. Did any of you find out if the backlight can be turned off?
