Hello,
I have made a prototype with chineese arduino uno clone and mcufriend 2.4" tft touch screen. The screen is the same as THIS ONE.

I'm now making a simplify custom board with custom regulator based on LM2576HVT-ADJ to allow 24V direct in.

The question is : Do i have to put a 2nd regulator to have a 3.3V or will it work without?

I don't have the prototype anymore and can't test by cutting the 3.3V pin. And thanks to chineese import delay i prefere sk to the community if someone knows.

Thank's!


PS : Sorry for my poor english.... I'm French ;)
