Cool

nice. vice clear

Eh

[@dominicxavier5274]

May I know why the crystal oscillator is required??

[@EDISON_SCIENCE_CORNER]

Ch340G requires crystal

[@mitalighosh7801]

You could have panelized them.
Then you could get more number of pcbs at the same rate

[@EDISON_SCIENCE_CORNER]

Thanks bro for Ur suggestion

[@thenextproblem8001]

Is it for 5v only? How about dual 5v/3.3v?

[@EDISON_SCIENCE_CORNER]

Yeah both

[@thenextproblem8001]

@@EDISON_SCIENCE_CORNER but how? When it's connected to USB it is 5v. So tx and rx should be 5v level too. Even if you are using 3v3 internal LDO of ch340. Can you measure RX and TX when you connected to USB? It may blow the ESP chips.

I think by using resistors
