Fermion: MEMS Microphone Module

This super - tiny MEMS microphone module is a real gem! It has an amplifier gain of 66. When there's no sound, it outputs a voltage around 0.66*VCC. When you speak, you can effortlessly capture the acoustic waveform through ADC sampling. It's compatible with all kinds of 3.3V/5V main - controllers, making it incredibly versatile. Here are its features: Signal Type is analog, it can run on a 3.3V or 5V power supply, has all - round directivity, a sensitivity of - 42dB, a S/N ratio of 59dBA, and a frequency range from 100Hz to 8KHz. Its compact size is 18*12.5 mm (0.71*0.49”). Included in the package are a Fermion MEMS Microphone Module and a 2.54 - 3P Black Single Row Pin Header. You can also refer to the product wiki for more details.

Using this Fermion MEMS microphone module is easy. First, connect it to your 3.3V or 5V main - controller according to the connection diagram. Once it's powered on, it starts working. When you speak near it, you can use ADC sampling to get the acoustic waveform. As for precautions, make sure the power supply voltage is within the specified 3.3V to 5V range. If the voltage is too high, it may damage the module. For maintenance, keep it in a dry and clean environment. Avoid exposing it to excessive dust or moisture, which could affect its performance.
