Hi,
I would to connect DFPlayer with software serial.
My question is:
It's possible to use only TX pin?
I need to play mp3 only, not receive info or any data from DFPlayer.

Thanks!

Yes, RX pin of MP3 module , TX from arduino  ;D

Tested and works fine, thanks!

In theory, yes.
The baudrate of the communication is 9600, softwareware serial port is enough to deal with it.
It only check the send command not the receive one. so only Rx should be work.( It should be RX pin for mp3 module, right? It is receiver pin.)
