Specification Brand : Generic BulletPoint : ADMP401 MEMS Microphone Breakout Module Board For Arduino Universal 1.3cmx1cm 1.5 to 3.3VDC With Pins ItemName : Generic ADMP401 MEMS Microphone Breakout Module Board for Arduino Universal 1.3cmx1cm 1.5 to 3.3VDC with Pins ItemTypeKeyword : sensor-blocks Manufacturer : Generic Material : Copper PartNumber : YGQ_MODULE_10718 ProductDescription : Material: Electrical Components Color: See Pictures ADMP401 3dB roll off at 100Hz and 15kHz 1.5 to 3.3VDC supply voltage Should comfortably output 40mW SNR of -62dBA This tiny breakout board features the ADMP401 MEMs microphone. One of the key advantages to this breakout and microphone is the bottom ported input This means the microphone's input can fit flush against the enclosure of your project Plus you will not have to deal with trying to solder the microphone's wacky footprint The on the breakout has a gain of 67 and more than meets the bandwidth requirements of the mic The 's AUD output will float at one half Vcc when no sound is being picked up The produces a peak-to-peak output of about 200mV when the microphone is held at arms length and is being talked into at normal conversational volume levels So the AUD output can easily be connected to the of a micro Size:1.3cm*1cm(0.51"*0.39") No Retail Package Quantity:1 Pc Notes: Due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you! Package Included: 1 x ADMP401 MEMS Microphone Breakout Module Board
