@Gerator - Nice project! How did you solve dual SPI channels for ethernet and RFM radio?

Ethernet gateway using Arduino UNO with Ethernet shield stacked JP1 should be 1-2 and JP2 2-3.

[Gerator]

RFM69 and Ethernet shield share SPI bus, each one with its own CS line. Ethernet shield uses pin 10 so JP1 should use pin 6 for the radio. Issues sharing SPI bus seems to be due to bad SEN line handling as described here. The official Arduino ethernet shield suffered from this, but most commonly used clones work ok. Shields including 74LVC14 as in the pic should work ok.

This project is very cool!

I received my pcbs to try it this morning , i'll tell you if i can make it work

[hlehoux]

Works perfectly ! So many thanks to @Gerator

[Gerator]

@hlehoux glad to hear that!!

Kind of a lot response. But would you be able to post schematics and BOM. I was able to but one of the DFRobot Arduino's and I want to give it a try. Thanx in advance

@TheoL Did you not check the openhardware site link? There it has the KiCad schematic and board files. In the schematic the individual symbols mostly have pdf datasheets. I see a passive without one, but that would be easy to figure out.

So it looks to me like everything is there that you need to make your own boards. I wouldn't hesitate if I wanted to make one myself.

Unless you were asking something else? But the design source files are there.

@ejlane I use Easy Eda and that can't import Kicad xd, maybe the pro version can, but I will never trust that enough to install it on my Mac. And I did check out the open hardwarw link. The comments come back to here.

I want to make one small adjustment. I wanna change the sma to ipex, so I have more choices in where to mount the antenna. Personally not a fan of an antenna sticking out of the side of a case.

But I guess I have to install KiCad to figure out footprints and schematics.

[ejlane]

Oh, I never even thought of that as a possibility.

I really like KiCad, and it's my preference. For a while I had Eagle for work, but even then I still preferred KiCad whenever I was given a choice.
