Wes had asked about these back in January. I finally found the parts and name and looked it up. Here's one of many hits, which is only one of many brands and versions of these things. https://www.mouser.com/new/rf-solutions/rf-solutions-gamma-915-modules/ I found the RF Solutions brand Gamma-915 a while back, at Arrow. The price was ridiculously low, like a few bucks apiece, while everywhere else they were $25 and up. I thought Arrow had a listing error, or was closing them out rock-bottom. Anyway, the price was right, so I bought out their entire stock about three dozen pieces. I like this model because it's old-school in board technology and size, so easy to work on and modify, it's in SIP form with 0.1" pinning, and comes with the antenna SMA mounted. There are all sorts of surface mount and much smaller versions too. I looked back at Arrow, and it seems they did close them out, but they are available at the usual places, at full price. If you're looking for the Gamma-915 (or 968 for non-US), be aware there are two models, 915 and 915R. I forget which is which, but one runs on 3.3V (or was it 5?) only, while the other has a LDO 3-terminal regulator to run over a higher up range. I bought the whole works, so have some of each kind. Ed
