RFM69W 915 mHz availability

Looks like the only RFM69W modules available to order are 433 mHz. Are more 915 MHz modules expected in?

Yes, I have those on backorder, seems like there's a factory bottleneck on those. I don't know when they might come in. At the mercy of Hope.

Stink. Thanks for the update. I will sit tight and wait for Hope to get them out to you.

Still waiting for updates as well...

Back in stock now, thanks for the patience.

Awesome, thanks for the updates! Placing an order shortly.

So... have you considered making/selling a breakout board for 0.1" spacing for these? Sparkfun has them, but they are for the "C" form factor.

Breakout?
I don't know, maybe. Too busy with other new products right now though, trying to get them published. But I have some ideas cooking in my brain. Just takes time...
The C is advantageous because it's pin compatible with the LoRa radios. So adafruit and SF are using those to avoid having to deal with so many parts. I support lots more radios because I don't have a million products and I am focused on Moteino and kits around them, plus people like having choices

Maybe I should have stuck with the Cs...

Wait a second... it looks like the RFM69HCW is pin- (or layout-) compatible with LoRa boards, but the RFM69CW isn't. So a single pad layout can support RFM69HCW and RFM96/RFM95, but not RFM69WW (or RFM69W)... right?

Right.

Right.

Figured that out the hard way with eagle today. Lol at me. Any way, this is a sophomoric effort, but I laid it out a limited (no DIO1-5) breakout for RFM69W and RFM69HCW/LoRa and I'm getting a prototype run done. It was a LOT uglier when I tried to have pads for RFM69CW and break out all the pins. I probably need to do more work on the antenna and ground too. Opinions welcome, feel free to use it if you like.
