As the Internet-of-Things (IoT) are becoming more and more popular, there is an increasing demand for low-cost and easy-to-use WiFi modules. For Raspberry Pi and BeagleBone, you can plug in a cheap USB WiFi dongle (like the popular Edimax 7811). These dongles are generally less than $10. But for microcontroller-based devices, the options are much fewer and generally more costly. For example, an Arduino WiFi shield can easily cost $40 to $50; even the more recent CC3000 module costs about $35. If you are puzzled by the big price difference: those cheap WiFi dongles require a USB host system, which is beyond the capability of Arduino. Still, it's unsettling to realize that a WiFi module or shield would cost more than an off-the-shelf WiFi router, even though the router is significantly more powerful.
