Wav trigger and due

Hi and thank you for your hard work and time.

I would like to use a due to trigger output sounds thru the wav trigger. I would like to use the softserial library and use the

Digital output pins to communicate via serial port of the wav trigger. Is there a voltage difference in the serial ports. I can’t find specs of the serial ports. I hope that came out right. Thank you

Wave trigger can tolorate 3.3V as well as the Due, so you should be good.

Thank you
