Check the datasheets, RFM69HCW has 16 pins, while RFM69CW only has 14 pins.

At least when I looked at the datasheets a couple of hours ago

Yes you are right. Sorry for the confusion.

Could we do what Moteino has done and drop support for HW/W radios and opt for HCW/CW/RFM95/96/RFM12 using double sets of pads?

Would be great if the community could settle on just one radio or a common way of doing things.

@bjornhallberg it is on the todo list.. First pcb are using the RFM69(H)W footprint.. As I already have samples of that pcb.. (still need to assemble though)

Hi Thomas,

I like this design! Can you please tell the status and your future plans for this design?

Thanks,
EVS

@evs

Currently I have the first prototype pcbs without components, so need to make an order at mouser/digikey. This has been on my task list for the last couple of months though, as wife / kids have a lot of other projects for me during the summer time :)

@tbowmo
Thanks for the update. But without the time frame. what needs to be done to finish. Is there software for the SAMD processor?

[tbowmo]

MySensors is already ported to samd21 so I expect things to be minor in order to get it up and running on samd20.

I will probably change footprint for the rfm69 module to use one that is compatible with rfm95 as well. And some other minor changes as well

[tbowmo]

A small update on this project, which I admit is taking longer than it should be (A lot of other projects has higher priority according to the wife)

I finally got the first prototype assembled saturday evening, I can upload firmware (via jtag/swd), and I have a semi hacked arduino core, that can build. But when programming the samd20e with this core, and a simple sketch toggling an output pin, nothing happens.

It seems that arduino halts in its initialization routine, waiting for some hardware to become ready after a reset, however I have not identified which part of the hardware yet.

@tbowmo

Hi, any update on this please?

[tbowmo]

Sorry, I got caught up in a couple of other projects, so still haven't got the first prototype up and run nok :(

Any luck with that at all? I really like they way the node is very small and with SAMD21

[tbowmo]

@alexsh1 bugger, I knew there where something that I had to do. The wife says that I have to finish the chicken coop automation first (opening / closing gates etc.).

[alexsh1]

@tbowmo ha ha ha - at least you are still married :)
