Add your ears to your project with this well-designed electret microphone amplifier.
This fully installed and tested board comes with a 20-20KHz electret microphone.
This escape is used for projects as an audio reactive project that uses the best voice changer, audio recordingmpling, and FFT. On the back we include a small trimmer pot to adjust the gain.
GND connects to the ground and VCC to 2.4-5VDC: It is easy to use.
The output terminal is a speaker or something you want to connect the amplifier directly to the speaker, then you will need an audio amplifier (such as our 3.7W stereo amplifier) is not designed to drive the smallest in-ear headphones.
