Regarding Touch Panel

On the Khadas’ EDGE V Pro board, There is connector J13 which is used for the touch panel connection, can you please let us know what is the use of MCU_TX (Pin # 8 of the connector) pin. And if we do not have that pin in our Touch panel will it be ok or not? or we have to tie that pin to High or low in the touch panel? If high then to which voltage?

At present, this pin has no use, so don’t care about it.


Thanks for the reply, But can you please let us know for which functionality this provision has made?
