## Description

The SparkFun Electret Microphone Breakout pairs a small electret microphone capsule with a 60× OPA344 op-amp preamplifier, making it easy to detect sound with a microcontroller's analogue-to-digital converter. Pick up voice, claps, knocks, or ambient noise — the amplified signal is ready to read directly from the breakout's output pin. Operating from 2.7V to 5.5V, this fully assembled breakout is compatible with both 3.3V and 5V systems. The microphone responds to frequencies from 100 Hz to 10 kHz, covering the range of speech and most common sounds. Key Features Electret Microphone Capsule – 100 Hz to 10 kHz frequency response 60× Preamplifier (OPA344) – Amplifies audio signal for direct ADC reading Wide Voltage Range – 2.7V to 5.5V operation Analogue Output – Outputs amplitude as a voltage signal Fully Assembled – Ready to use out of the box, no soldering required beyond headers Compact Breakout – Small footprint for easy integration Ideal For Sound-reactive LED and light projects Clap or knock detection Voice activity and noise level monitoring Arduino and microcontroller audio input Resources Hookup Guide Schematic (PDF) Eagle Files (ZIP) OPA344 Op-Amp Datasheet (TI) Microphone Datasheet (PDF) Hardware Design Files (GitHub)
