{"NAME":"TTGO T4 v1.3","GPIO":[35,1,672,1,992,1024,1,1,832,768,736,704,1,1,896,0,0,640,608,864,0,0,1,6368,0,0,0,0,6400,1,1,4704,1,32,33,34],"FLAG":0,"BASE":1}

Tested on Tasmota 9.3.1(display) and 10.0.0(display)

Display settings:

Backlog  DisplayModel 4; DisplayRotate 0; DisplayDimmer 100; DisplayWidth 240; DisplayHeight 320; DisplayFont 0; DisplayCols 39; DisplayRows 40; DisplayRefresh 1; DisplaySize 1; DisplayMode 5;
  • You may need to press [Toggle] to turn the display on
  • DisplayMode 0 does also work
  • If the SD Card reader works is unknown.

Tested on Tasmota 9.1.0(display), 8.5.1(display) and 8.4.0(display)

Somehow DisplayMode 0 does not work on these versions.
