connect to ortur master 2 control board

[j-lang]

Only a question: is it possible to connect the ESP8266 board to the ortur master 2 control board?
If yes, is there a connection diagram?

for what I know it is not possible as the board does not provide an external serial connection, or rather, the card has a header for the serial connection but the ortur firmware does not enable it.

Ok, searching for information i think that the offline conector have 5v, GNd, TX and Rx

I think its posible
Thanks for everything, forgive my poor English and my little knowledge of electronics and programming. I will buy the resistors and others and I will try. I would love to know if as pro you see it possible. a strong greeting
