I just now posted the files for Version 2.

I just now posted the files for Version 3, which allows for an 0805 cap across the Ra-01's 3v3 and GND pads. I just now sent Version 3 to the PCB fabricator.

Project completed. It works.

It runs the RadioHead RH95 library and examples without any need for modification.

Nice work! Any chance you can post some code samples to interact with MySensors gateway?

[NeverDie]

@miljume

Not anytime soon. Probably better if someone else did.

[pansen]

Out of curiousity: Why did you use a through-hole AVR and not a SMD one?

[NeverDie]

@pansen

Easier/faster to solder.

@NeverDie

I understand but tend to disagree

[nitroburn]

any ideal value for the radio decoupling cap? It is the only thing I don't see listed.

I'm not sure that it's even needed. I added pads for it in case it might later prove necessary or beneficial, but for now it's optional (unless/until proven otherwise).

Is it working ? How to upload sketch using FTDI right

[giridhararm]

Is it working can I use FTDI to post rfm libraries

[NeverDie]

@giridhararm yes

Starting with MySensors Release 2.1.1, it appears this module is now supported by MySensors:
"New transport layer: RFM95 (LoRa mode)"
