MQTT Message Queue support for W5500 eth module
Hello,
on wiki you can found an implementation of MQTT, a small machine-to-machine/"Internet of Things" connectivity protocol, as expansion of W5500 eth module.

Thanks for all the wiznet modules, Coccoliso. You've made it pretty easy to use... I might have to pick one up and give it a try.

Hello Jerry,
excuse is slightly off topic (but Firewing is of the same family
)
David suggested to me an itead shield http://imall.iteadstudio.com/im140725005.html which at first glance should work with Firewing ..
Someone has tried it?
Thanks.
PS: Then move any replies in FW forum![Wink :wink:](./images/smilies/icon_wink.gif)

Yes, it's ok to discuss Firewing on this board - given that there are both Firewing and Swordfish modules for W5500, I think it's certainly OK to do that...

Re: MQTT Message Queue support for W5500 eth module
In that case...
This might already be in the wiki/forum somewhere, but I found these available at Mouser here in the States:
WIZ550io
ioShieldA
The pair is about the same price as the single board from itead, but w/out the POE capability. The single board is a good bit smaller since it's not a shield + plug on module.
I'll put a link over on the Firewing forum to this thread in case anyone is looking for available hdw.

Re: MQTT Message Queue support for W5500 eth module
Just to clarify a bit, the ioShieldA includes a WIZ550io module (so it's the shield + 550 module). I didn't realize that at first.
That makes it quite a bit cheaper than the POE Itead one, about $22 USD.

Re: MQTT Message Queue support for W5500 eth module
The Itead module may be a better choice after all.
I just went to hook up the ioShieldA to a Firewing08 board and found that it's not really compatible w/out some mods.
You have to remove a header since the ioShieldA has the SPI signals connected to the Arduino ICSP connector and not the normal place.
Mostly just adding jumpers to move some of the signals around, but you have to watch because the ioShieldA will short 5V and 3V3 if you don't do the changes!
The attached has a pdf showing the ioShieldA schematic and modifications.

Re: MQTT Message Queue support for W5500 eth module
Yes Jerry,
Itead is one of the few that uses the SPI pins on the connector D9 / D13 instead of the 6 pin Arduino ICSP central header, that in some cases could also touch the ICSP Firewing header if it is mounted.
