Microphone Module Board PCB 1.5～3.3VDC ADMP401 1.3 X 1cm☜
Feature: \n 1. The amplifier module on the breakthrough has a gain of 67, which exceeds the microphone bandwidth requirement.\n2. When no sound is received, the AUD output of the microphone module will float at one\u2011half of the volt current condenser position.\n3. When the microphone keeps a certain distance from the arm and speaks into the microphone at a normal dialogue volume, the module in the amplifier will produce a peak output of about 200mV.\n4. The input of the bottom port can be flush with the shell you make, which can reduce additional welding.\n5. This AUD output can be easily connected to the ADC of the microcomputer. \n\nSpecification: \n\nItem Type: Microphone Module\n\nMaterial: PCB\nPurpose: Suitable for college students, engineers, technicians, factories, individual , electronic enthusiasts and other operation learning\nPower Supply Voltage: 1.5\uFF5E3.3V DC\nOutput Power: 40mW\nSignal To Noise Ratio: 62dBA\nSize: Approx. 1.3 x 1cm / 0.5 x 0.4in\n\nPackage List::
