Adafruit Wired Miniature Electret Microphone

Key Features Wired Electret Microphone about the size of a mature aphid Perfect for your FONA Pre-attached 65mm long wires That's one tiny microphone! At about the size of a mature aphid, this wired Electret Microphone is perfect for your FONA.This microphone's very similar to our PCB-mount Electret Microphone but is significantly smaller and has pre-attached 65mm long wires. We don't have a specific datasheet for it but it can be biased with 2V and 2K impedance. 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.Item SpecificsDiameter: 4.4mmWire Length: 67mm Weight: 0.17g
