I see that there is 5V to 3.3V converter that power the display chipset and touch chipset with 3.3V, then i will have TTL on 3.3V on all LCD/TOUCH pinout ?

You see, if you apply 3,3V to VCC you have to bridge JP1.
You can also 5V direct to the Pin(then without the bridge).

If i bridge, must i to remove IC regulator from PCB. For me looks and short circuit if i put the jumper, or, am i wrong ?

Thanks for help that you are giving me!

Btw, i powered with 5V, then the display stops to work!

I have the same display
Also had a problem reading the touch data,
Connected the display as in the documentation, output checked, the output level of the touch controller was to low.
Something was shorting the output.
I disconnected the sd-out from the display controller, and my levels where ok
The touch was recognized by esp basic
The display works fine, as espbasic is only writing to it.
Hope this also solves your problem
