This Allstar node is as easy as it gets!
Hardware setup.
Buy a MPOW PA071A headset/mike as shown in the photo.
Plug it into one of your Raspberry Pi USB sockets
That is all there is to it, that’s all you need as this particular headset actually contains a CM108 sound fob in its inline control unit. And the volume down button on the headset control functions as a PTT button. This headset is cheap to buy, and the sound quality on the operational nodes is outstanding, I have one running at my QTH right now.
