Feature: 1. This carefully designed electret microphone amplifier can add a lot to your project. Fully assembled and tested circuit board with soldered 20-20KHz electret microphone. The output pins are not designed to drive speakers or the smallest in-ear headphones, but to connect them directly to the speakers, so you need an audio amplifier (for example, a 3.7W stereo amplifier).
