Can you please tell me what type of Microphone is used for this circuit

In reply to BorisLandoni. Ok thanks!

In reply to Caleb Pike. XLR is normaly a balanced signal, so you need another circuit

Great writeup and project! Would one be able to use an XLR port instead of the mini mic you have on the board?

In reply to Dave Coles. I think less than 2mA

Hi, how much current/power does this circuit typically draw? Thanks.

Would you list the preferred values of the resistors and capacitors used for these calculations?
