FAQ

What are configurable mechanical components?

Configurable components are products in which you can select specific design features, and see the price and delivery times at a glance.

The most used configurators include linear shafts, linear guides, miniature linear guides, aluminum extrusions and aluminum sheets. Select your specifications from material, surface treatment, length and diameter.

Description
This electret capsule microphone is the same one Adafruit use in their great microphone amplifier board. It contains a small vibrating element that will output a few milllivolts peak-to-peak.
You will need an op-amp to amplify the signal, some chips are designed with the amplifier built in in which case you can wire it up directly.
This is an "omnidirectional" microphone, with -44dB sensitivity, and has 20-20KHz frequency response. You can plug it into a breadboard or perfboard or solder wires to the little wires sticking out the back.
Check out OpenMusicLab's great tutorial on Electret Microphones for a deeper look at how these sensors work. If you need an amplifier board, see Adafruits fully-assembled and tested mic amp board with adjustable gain.
