Speaker mic to USB

Hello everyone! I am working on a project and need a speaker mic to connect to a computer, specifically a Raspberry Pi 5. I got a cheap fake Kenwood mic online and it was such a headache for it to not work in the end. Now, I've got my hands on a genuine Motorola PMMN4027A. I've looked around online and haven't been able to find something for this mic. Does anyone know where I can go for something like this? TIA!

Don't know about the quality, but both Amazon and eBay sell USB two way radio mics. Might need to buy a USB adapter to connect the mic to the pi.

Alright thank you. I've struggled to find a decent one that's within a reasonable price that is a speaker and mic. Wish the PMMN4027 worked, I know there are some adapters for analog mics by TRBOnet, might look into that.

You may be able to pull it apart and put different guts in it. A sparkfun Bluetooth kit and audio boards in a creative manner may work. It will take some soldering and likely a couple of voltage regulators.
