{"title":"SparkFun Electret Microphone Breakout","handle":"sparkfun-electret-microphone-breakout","url":"/products/sparkfun-electret-microphone-breakout","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.\n\nOperating 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.\n\nKey Features\n\n\nElectret Microphone Capsule – 100 Hz to 10 kHz frequency response\n\n60× Preamplifier (OPA344) – Amplifies audio signal for direct ADC reading\n\nWide Voltage Range – 2.7V to 5.5V operation\n\nAnalogue Output – Outputs amplitude as a voltage signal\n\nFully Assembled – Ready to use out of the box, no soldering required beyond headers\n\nCompact Breakout – Small footprint for easy integration\n\n\nIdeal For\n\nSound-reactive LED and light projects\nClap or knock detection\nVoice activity and noise level monitoring\nArduino and microcontroller audio input\n\n\nResources\n\nHookup Guide\nSchematic (PDF)\nEagle Files (ZIP)\nOPA344 Op-Amp Datasheet (TI)\nMicrophone Datasheet (PDF)\nHardware Design Files (GitHub)\n","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":12999,"title":"Default Title","sku":"SF-BOB-12758","price":19.43,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":48,"option1":"Default Title"}]}
