The microphone input fits at the same height as the project's enclosure!
This product is a microphone sensor equipped with an ADMP401 MEM microphone, capable of bottom-port input. There is no need to solder the tightly packed footprint of the microphone. The gain of the breakout amplifier is above 67, meeting the bandwidth requirements of the microphone, and when no sound is detected, the amplifier's AUD output floats at half of Vcc. When spoken at normal conversation volume, the amplifier generates approximately 200mV peak-to-peak output, allowing the AUD output to be easily connected to a micro ADC. 【Features】 ■ Equipped with ADMP401 MEM microphone ■ Bottom-port input ■ No soldering required ■ AUD output floats at half of Vcc when no sound is detected ■ AUD output can be easily connected to a micro ADC *For more details, please refer to the external link or feel free to contact us.
