What are the voltage specs for the UART TX/RX lines?

The voltage specs for the UART TX/RX lines is 3.3V

Many sounds stop with a weird, loud glitching noise. How do I prevent? Is there a preferred format? Bad unit? I am using 16-bit wav 44.1k mono

1. It is recommended to use MP3 or WAV format music files 2. Use a 4ohm(<20W) or 8ohm(<10W) speaker, otherwise it cannot be driven, resulting in abnormal playback; At the same time, pay attention to provide sufficient power supply 3. The wire must not short circuit

I have a photoelectric pnp 900ma output ir sensor. need this to play a single song once that sensor detects an object. will this work? connections ?

I purchased this device because it seems to have the ability to play a different sound file individually based on closing one of 7 contacts. There are a number of small modules that will play a single mp3 file with the closing of a contact that appears to be much easier to set up and configure. This item came in an envelope that contained absolutely no paperwork or even a link that I could see. So, the only data on its use appears to be what I can get off the Amazon sales page. I hope this helps. Good luck trying to figure out how to use it.
