@AarooneyFarr - There are a few differences from BOX3 to BOX:

• It has no Accelerometer
• GPIO47 is the Backlight, while BOX uses GPIO45
• GPIO45 is the I2S LCLK, while BOX uses GPIO47
• 2 options for Display + Touch Screen => ILI9341+GT911 or ST7789+TT21100
• BOX3 has SD_MMC + SD Card Slot

Do you already have any project in a public repository?

Hello, this will be covered by BSP (Board support package) from @me-no-dev, adding to 3.1.0 milestone. The tasks is now in the progress but is blocked by 3.0.0 release.

@AarooneyFarr - I have just added an Adafruit GFX based driver for the ESP-BOX-3 that you can test and use.
In order to use it, it is necessary to select the ESP32-S3-Box board and code of the library will change the TFT_BL pin to 47, instead of 45 when ESP32_S3_Box_3_TFT.h is included.

If necessary, I2S_LRCK pin has to be changed to 45, instead of 47.

The example in the repository runs the Adafruit GFX demo and also prints the touch point in the Serial Monitor. It also allows "finger painting" (using touch) at any rotation mode, at the end of the GFX demo.

Have fun!

I also just realised that there is an effect with Serial.print() in the ESP-BOX-3 when the GFX demo sketch is run with no open Serial Monitor. This is a sort of delay in every Serial.print() from loop, related to some issue with the USB HW JTAG CDC driver.

In order to avoid it, it is necessary to disable Serial, by commenting out the Serial initialization:

void setup() {
  //Serial.begin(115200);
  //Serial.setDebugOutput(true);
  //while (!Serial) delay(100);
