SparkFun Electret Microphone Breakout
We have ✅ 2 available of the SF-BOB-12758 in our Sydney warehouse. An extra 26 units available with a short lead time.
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.
