MAX4466 Electret Microphone Amplifier Breakout with Adjustable Gain

Add an Ear to Your Project This fully assembled and tested electret microphone amplifier board makes it easy to add audio input to your electronics projects. A 20–20kHz electret microphone is already soldered on, so you can start capturing sound straight away without any additional wiring or setup. Adjustable Gain Control On the back of the board, a small trimmer potentiometer lets you adjust the gain from 25x to 125x. This gives you flexibility to match the sensitivity to your specific application, whether you need a subtle pickup or a more sensitive response. Clean, Reliable Amplification At the heart of the board is the MAX4466 op-amp, chosen specifically for microphone amplification. It features supply noise rejection, which keeps the output clean and free from the scratchy background noise often found on other mic amp breakouts. The result is a noticeably clearer audio signal for your projects. Ideal Use Cases This breakout is well suited to voice changer builds, audio recording and sampling setups, and audio-reactive projects. Its compact design and straightforward connections make it a practical choice for hobbyists and makers working on sound-based electronics.
