Questions about the ovc3860 (Or the XS3868 module)


I've been wanting to integrate this module in one of my project but I have some questions about it:

  1. can you pair two of this module together like with the HC-05?

  2. Doe the Audio output have enough power to get it right into headphones or you need an amplifier for that?

  3. How does the microphone input works? can audio be transmitted to a phone that connects to it or another module?

  4. What's the maximum current output for the 1.8V output on the XS3868 module?

Thanks for your time.
