Description

Adafruit Electret Microphone Amplifier with Adjustable Gain is fully assembled and tested board comes with a 20-20KHz electret microphone soldered on. For the amplification, the Maxim MAX4466 is used, an op-amp specifically designed for this delicate task. The amplifier has excellent power supply noise rejection, so this amplifier sounds really good and isn't nearly as noisy or scratchy as other mic amplifiers breakouts are tried. Small trimmer pot on the back to adjust gain (25x to 125x). This breakout is best used for projects such as voice changers, audio recording/sampling and audio-reactive projects that use FFT. On the back, a small trimmer pot is also included to adjust the gain. You can set the gain from 25x to 125x. That's down to be about 200mVpp (for normal speaking volume about 6 inches away) which is good for attaching to something that expects 'line level' input without clipping or up to about 1Vpp, ideal for reading from a microcontroller ADC. The output is rail-to-rail so if the sounds gets loud, the output can go up to 5Vpp. Using it is simple: connect GND to ground, VCC to 2.4-5VDC. For the best performance, use the "quietest" supply available (on an Arduino, this would be the 3.3V supply). The audio waveform will come out of the OUT pin. The output will have a DC bias of VCC/2 so when its perfectly quiet, the voltage will be a steady VCC/2 volts (it is DC coupled). Connect the OUT pin directly to the microcontroller ADC pin. It is RoHS compliant.

  • Great microphone for your Arduino projects!
I used this product to create an bass responsive LED clock. Now my beats create amazing light shows! This product from Adafruit comes with easy to find/use information on how to use it and implement it into an arduino project; this makes getting started with it easy. It can be used to identify amplitudes of different frequencies with an FFT library in arduino (Though the higher frequencies seem to display a lot of noise from my tests.) you can also simply use the device to record audio 'loudness' and can be used as a form of human presence sensor as people tend to make a lot of noise. In fact I purchased a second one for a project to identify human presence where I will use it along with a list of other sensors to identify if someone is in the room. Overall I am very satisfied with this product as it allows you to add the functionality of a microphone to a project without having to develop complex circuits or prepare software for it. ... show more

  • 4 1/2 stars, works as described
In reality this is more likely about 4 1/2 stars instead of 5. Would have been nice to have the pins pre-soldered but was not a big issue. A small hassle to find example code to test this out but I would recommend going to the actual Adafruit site and running their supplied code. Yes, this microphone is not that sensitive. It is smaller than a quarter and didn't claim to be that sensitive. HOWEVER, for me at least, this is a very simple fix. For example, if you are trying to decipher something like a clap then do a little testing, and change the threshold corresponding to where you want to sense the clap from. All it takes is changing the threshold that "detects" the clap. Granted the distance from the microphone can make the clap register a very different value but that is not the microphone's fault. Use multiple at different position if you have to. Works well and does as described. Will update if I have issues. ... show more

  • reasonable priced sound input unit
Works exactly as advertised. Running off the logic supply is handy. Recommended.

  • Tiny but powerful.
It works. Haven't had any errors with this yet. Connected it to a matrix board s3 from the same company (Adafruit). It picks up sound correctly as intended for my use.

  • Great little board with just one minor problems
I use these in a lot of my speech recognition projects. Normally, I use these as breakouts for the MAX4466 preamp chip, discard the mic that comes with it, and put in a first order directional element (cardioid or dipole). The only problem is that there is zero protection on the audio output line. If it comes into contact with the bias supply, the MAX4466 is gone instantly, so do not wire these to a TRS connector, you'll blow the board the first time you plug it in. They're fine with mini XLRs. ... show more

  • This is a great mic but ran a little hot for my setup ...
I use this with a custom 3.3V regulator. This is a great mic but ran a little hot for my setup so I installed a 22KOhm resistor in series with output. Very nice and durable. I have used 13 in different mic setups and have only had one go bad due to shorting in my power board due to sloppy tech work which was no fault of the boards. Highly recommend this unit. ... show more

  • I like that you attach pins yourself so can decide on straight or 90's-Only straight provided, I installed 90's
Nice little microphone I'll use for playing around on a breadboard. The pins that come with the microphone are straight as shown in the unassembled picture of the product. Not sure why they provide these instead of the 90 deg pins shown on the assembled unit. I wanted 90 degree pins on mine so installed some from my stock. That's one thing I really prefer about buying components that you finish yourself. You can configure them to suit your own needs. ... show more

  • Poor production quality
The Adafruit Electret Microphone Amplifier - MAX4466 with Adjustable Gain is worth what you pay for it: very little. I bought two. One was DOA and the other had a frozen potentiometer with solder in it. It worked at the level it was frozen at, but trying to get it unstuck damaged it and now it doesn't work either. ... show more
