The WizFi210 is so new I cannot find a datasheet but the link below has a schematic of the evaluation board. The $30 price makes it very attractive for a shield.

has the user manual in the downloads section..
Thanks - I had clicked that tab but nothing happened.

Links do work, justdownloaded pdf.
When I click the link, the page jumps as if scrolling down a few lines, but nothing else. Clicking a second time loads the linked page.
Given the low cost of the WizNET devices, I'll try to design a shield that can support the WizFi810 and the Wiz107SR. They are not quite as easy to use as the Connect One modules nor do they have SMTP/POP3 and other protocols built-in but users might be able to adapt Henrik's low level code (once completed) to work with these.
It looks like the Wiz105SR is their only ethernet-to-serial module without either an RS232 or RS485 transceiver. It has a SMH header on top of the board which would make it hard to use with a shield that also supports the WizFi210 but I may buy one to see how difficult it would be to modify.
That should have read SMD. Anyway, the Wiz105SR just barely fits on a shield PCB with enough room left over to squeeze in a 2x6 header that can connect to the module via a ribbon cable. So, while I'm waiting on answers to a couple of questions, I'm fairly sure I'll design a shield for the Wiz105SR and the WizFi210. Both are among the least expensive modules of these types. If so, I'll drop the shield design for the Tibbo modules - I really don't like how long Tibbo took with firmware updates nor do I like the Goldbergian interconnect method they used between the EM500 and GA1000 and flash.
Hi Dave,
I looking at this also. I have a project in mind that would appeal to the hams here AND elsewhere.
It is a wireless UNencrypted link using either channel 1 OR 6. The reasons for this is to increase range.
Any thoughts or suggestions would be very helpful.

I'm still waiting on answers to a few questions I sent to their US dealer. The manual for the WizFi210 shows several pins that either have internal or need external pullups/pulldowns. The manual is ambiguous and I'm not sure whether I need to add external resistors. There are a few other things like that - are the inputs 5V tolerant - some of their other modules are. With 48 pins, doing level conversion on more than 2-3 is a non-starter. The WizNet website has a FAQ and Question/Answer database but looking there has been unrewarding. They have a User Forum but it's in Korean.
It looks good and there's a high-power version WizFi220 but I'd feel much better with clear documentation and a way to get questions answered.
I've designed a shield for the WizFi210/220, Wiz810io & Wiz105SR but don't want to order PCBs or modules til I feel better about all the above.
Thanks Dave,
I know what you mean about getting data sheets. It's very frustrating at times getting simple answers..
Hey, have you tried Jameco, who is a US distributor?
Thanks again,
Terry K9HA
I tried Saelig who have been pretty good in the past but not this time. I'll try Jameco - I missed that they are a distributor.
Dave,
Go back to Wiznets site and follow the link to US Distribs, several US didtributors.
Happy to help,
Terry K9HA
Jameco's price is too high and they have no datasheet - only the quickstart guide so I doubt they can answer my questions.
Neither SparkFun nor Future Electronics stock it.
Hi
I have to agree with dhouston
"

That's right, I sent them message and they couldn't answer my questions properly. Probably some random people sitting over there and answering customers questions.
