🔊 HiLetgo Electret Microphone Amplifier MAX4466 Module: Adjustable Gain Blue Breakout Board for Arduino - 2pcs Set Review

Bought 5 pieces from another seller but they end up not working. Bought these jumps, they worked and they worked! Will buy more if I need more!

Works great - first mic I installed and works great, now I'm designing a PCB to connect all the components for this project. Great price for two microphones

Works very well and seems to match the advertised characteristics. I've used it to play around with beat detection and FFT and it seems to do exactly what I expected.

A good microphone for DIY projects. It only has three connections: power, ground, and signal. It's amplified, but I've found it works better when the sound is close. I plan to use it for sound detection by a small robot.

Haven't used the mics but they look good. I will review this review within two weeks as I should be able to work on this project by then. I'll provide some sort of status update.

The microphones arrived and I soldered the pins to one of them (I couldn't get a reliable connection without soldering). I've never soldered before so it was a little tricky, especially given the size of the joints. Now everything works as expected and I have no complaints. I haven't tried the second one yet, but I find it hard to believe it won't work

I see there are many good reviews but these mics need to be very close to what they are supposed to pick up. I tried to do a musically reactive display with them. Unless the speakers playing music are a few inches away from him, he won't record anything. The little knob on the back of the mic doesn't seem to adjust the sensitivity.

They are very cool and accurate. My Arduino gives me a nice wide range of values to use. There are other mic pickups WITHOUT an amplifier and let me tell you they are NOT worth the time as they return noisy and inaccurate readings. Try these - I use them for robotic eyes that wake up when you talk, open wide when you scream, and fall asleep when you're silent.

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…
