What is stopping me from soldering this mic to a 3.5mm jack and plugging that directly into the microphone input port on the back of my computer. Seems like a cheap and easy zoom call microphone?

Hi @Pixmusix

I see no reason that you couldn’t do that, my only though is that the quality of the mic probably wouldn’t be the greatest.

Hi Pix

I can think of a couple of reasons.
The Mic breakout has to be powered. It probably is an electret type as there is a connection to Vcc.
There will be a DC voltage on the output of half Vcc. This will require a series capacitor on the output to remove this.
It looks tile there is a direct microphone output (bypassing the OpAmp) available but the level might not be enough and if there is any DC present it will have to be removed with a cap.
A lot of this would depend on exactly the PC input looks like. For Zoom a lot simpler to use a USB mic.

Yeah thats a pain hey.
Good think Bob. Ill look for an off the shelf solution.

Fair. Thanks Dan.

Hi Pix

I have a USB mic that I was using for video annotation. Works pretty well. Forget where I got it now.
Cheers Bob
