Hello guys,

I need to wire both ESP8622 and touch panel JZ-TS35 to RAMPS1.4. Those two originally uses AUX1 (5v GND D0 D1) working pretty fine alone, so I need to wire one of them on other Serial port to use them together , but I don’t know which on to use (AUX2, AUX3....), and also which pins to use for communication as TX RX (D41, D43...). Could you guys help me?

Thanks

The main firmware doesn't support that, designed for one input serial port.... Also all the other mega pins that can be hardware serial ports are used for other things. (endstops mostly)
And there is the 5v vs 3.3v levels to worry about also...

JZ-TS35 screens are designed with this in mind and has its own wifi plug to do this for you.
