Title: RFM69W 915 mHz availability
Post by: jordanmills on July 09, 2016, 10:53:18 PM
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.

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.
