Review on 🎤 Adjustable Electret Microphone Amplifier by Adafruit by Alyssa Bell

I use them in many of my speech recognition projects. I typically use them as connectors for the MAX4466 preamp chip, throw away the included mic, and plug in a first-order directional element (cardioid or dipole). The only problem is that the audio output line is not protected. If it comes in contact with a bias source the MAX4466 will fail immediately, so don't connect it to the TRS connector, you'd burn out the board the first time you connect it. They are suitable for mini XLR.
