They offer mini and (soon to be released) micro cards. I assume (or better I hope ;)) they use the same chipset as your SDW-820, but I don’t know. Is anyone interested in investigating in this card? Drop me a note and we can arrange something. I am absolutely willing to sponsor a few of such cards if you guys are looking into developing/re-engineering a driver! Let me know! I ultimately want to run the card without OS, so just a microcontroller/-processor and the card!
those of you interested in playing, some guy has posted the data sheet for the Intersil Prisim data sheet for the Spectec 820 card on the web.
I too have gotten this document but i have an NDA signed with Spectec. He should not have posted it, so you need to nab it while you can, before they realize that its a NDA document and remove it.
i was also playing with the Airdrop system myself. i made a board that pluged into my LPC2378 kit then to a CF connector. i wanted to use the IO directly to the card and none of this latiching crap that they use to mimic a data or address bus. i got it working ok, with the examples given, then i was going to add the TCP stuff. as i leaned back in the chair and looked over at my shelf is when i saw the SD WIFI card and since there was a SD connector on the board i said what the hell am i doing. i am tieing up all this IO when i can just use a few simple IO lines to do the same thing. so i stoped working on the CF version and am all geared up for the SD version. My goal is speed. i have a project in mind and i need high throughput rates. however, i dont see why a guy with a very small micro like an Atmega8 to be able to get on the net, hell even a 8 pin micro could do it given enough ram and flash.
I too am very intereted in this project. I have a 2148 and sd-card interface that I could use.
I will try to get the Spectec, could the originator post a supplier in the US?
Also a consideration is unit cost and availability. I found this one on compgeeks.com, and google turned up a reseller (Evertek wholesale) selling these by the pallet load (3400 per pallet). Think it may be usable? Its an Ambeon 54mbps 802.11b. $31 each at compgeeks.

Man, it seems like im the only guy interested in this SDIO-WiFi card stuff.
Anyhosel, i am now at least getting responces back from the card now.
You’re not the only person with interest in driving an SDIO-based WiFi card. The problem I see is that it’s probably going to be impossible to write a “class driver” that covers all SDIO WiFi cards and, hence, you’re pretty much doomed to be in the backwaters. I did a lot of work on a CF-based WiFi solution with the AirDrop but ultimately decided it was going nowhere as the CF format just doesn’t have that much traction now.
