maybe this little ( 8mm x 8mm) wifi board is worth looking at.
It’s small, supports b/g/n, SSL, IPV6, AP, WPS, OTA FW and more … have a read.
If you look further through their products EC32Lxx range you’ll find something very interresting (thx to Valkyrie-MT pointing that out) it is partnered with an MCU you’ll probably know.
But that could be for the fact that they are just announced, early January 2014.
I’ve asked the European sales office in Greece and they, the sales office, responded they, the EC19Ds, will be on sale after February 15th. Hmm, next year is after feb. 15th as well … we’ll see …

As we know, CC3000 module is not on sale yet, so I made my own one for testing proposes. Is important to say that it works great with cerbuino bee (using the libraries in this post).
Problem: when I plug the module in the sockets 3 or 11 (s type) of my brand new Raptor, makes the Raptor boot as a GPS. Like when we have to initialize mainboards in boot-mode. I am working on socket 1. I cant make it work, but at least it boots as a Raptor.
I just realized that I can’t solve my issue alone.
I’m getting 040404 or 010101, like a clock. Previous in this post, Valkire had the same problem, but I don’t find a solution for it.
As this issue appears only for Raptor (works fine with cerbuino) I added the recommended resistors, I “pull-uped” MISO trying to make Raptor similar to cerbuino. Nothing works.
Now the cc3000 module works better on cerbuino but still failing on Raptor.
If someone solved this problem, please let me know how.
Thanks again.
Embedded WiFi Module - 802.11 b/g/n Industrial Temperature HF-A11 for $18.20
The HF-A11 can operate in Infrastructure Station (STA) mode, Soft Access Point (AP) mode or AP+STA mode. Support for Router/Bridge mode networking is also provided.
It’s certainly good to have hardware choices. It is difficult though to assess the firmware quality of such modules (CC3000 was a reminder of this fact), and even with good hardware and firmware, we still need a high-quality NETMF driver for it. That’s where the real challenge lies, and the blood, sweat and tears.
@ Cuno - Yeh, you’re right. But we’ve got to start from somewhere in order to bring the cost of IoT connectivity down. Cost of WiFi add-on >= $70 is way too much!
I also believe that Ti is on the right track w/ their new CC3100/CC3200 series.
@ andre.m - Power consumption is usually tied to output power. Check the specs, probably one has more transmit power (in dB or mW) than the other. So low current is not always better, depending on the range you want to cover with these WiFi modules.
Probably there is someplace need to be perfect. I think we are still able to support customer. SPI function is reserved, customer need to develop it based on the SDK.SDK can be download from our web. The default interface is UART.
any questions, feel free to contact me.
