Review on πŸ”Š HiLetgo Electret Microphone Amplifier MAX4466 Module: Adjustable Gain Blue Breakout Board for Arduino - 2pcs Set by Melissa Walker

Revainrating 5 out of 5

It is excellent.

Not only can they be used as sound level sensors in many projects, but they can also be used as real microphones that can be connected directly to a preamp, mixer or A/D converter. . If you use a 5 volt supply, the output levels will be close to 5 volts, even because of background noise, and any intended input signal will be clipped. Using 3.3 volts on an Arduino or Pi gives you about 2 volts of ground, which eliminates most clipping. There is a bit of noise at the output so I'll try 2.5 volt VCC. Great find.

  • Don't waste too much time
