Perhaps the cheapest radio interface which includes programmatic?PTT control and works with Dire Wolf appears to be the DINAH AllStar designed interface.? Assembled with shipping is about $53.
A discussion of a design using this interface and Dire Wolf can be found at:

The DINAH is described at:

There is a version of DINAH available which is a stackable hat for the PI Zero W/PI Zero 2 W.? It is available form the DIANH supplier.? A picture is attached below.

And also the NINO-TNC.? Much less expensive than the DRAWS hat if you don't need all the features...
And the NEXUS DR-X which still requires a sound card and direwolf, but will control 2 rigs seperately

A signallink?will work, but is pricey and uses an onboard VOX approach.? There are cheaper interfaces which use the CM108 PTT control which is supported in Dire wolf and provides programmatic?control of PTT through?the 6 piin mini-din interface.
