New WiFi Module

[dhouston]

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,

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,

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.
