content: They are available on ebay as mobile phone spare parts.http://www.ebay.com/itm/New-Mic-Microphone-for-Nokia-6500-Classic-5800-8600-UK-/300517621639?pt=LH_DefaultDomain_3&hash=item45f83eff87Need to mention that they are very delicate. Overheat it a bit while soldering and it's dead, flux gets inside - it's dead, try to clean it with IPA - it's dead.

content: Quote from: Isad on March 22, 2015, 09:09:34 amHuh, cannot build simple preamp but trying to use mems mic? You are strange indeed. Like this thing is too hard to make, i'll take something even harder. BTW for this microphone from digikey which have analog output, you need to build preamp too. Preamp circuit will be exactly the same as for simple electret micropfone except you don't need one additional resistor as it have separate power pin. BTW you say record on PC. You can attach electret microphone to the PC microphone input directly without any additional circuit. PC mic inputs are intended to attach such mic directly, there is a preamp already.
