## Description

That's one tiny microphone! At about the size of a mature aphid, this wired Electret Microphone is perfect for your [FONA](https://core-electronics.com.au/adafruit-fona-mini-cellular-gsm-breakout-ufl-version-v1.html).

This microphone's very similar to Adafruit's [PCB-mount Elecret Microphone](https://core-electronics.com.au/electret-microphone-20hz-20khz-omidirectional.html) but is significantly smaller and has pre-attached 65mm long wires. Adafruit don't have a specific datasheet for it but it can be biased with 2V and 2K impedence. You do need an electret microphone amplifier to boost the millivolt-signal up to line level. The FONA has this amplifier part built into it but something like an Arduino does not.

Adafruit tested it with the FONA and it works great for voice purposes, you may also be able to use it with Adafruit's other microphone amplifiers (like [\#1713](https://core-electronics.com.au/electret-microphone-amplifier-max9814-with-auto-gain-control.html) and #[1063](https://core-electronics.com.au/electret-microphone-amplifier-max4466-with-adjustable-gain.html)) and if you desolder the onboard microphones.
