* It is very easy to develop projects with AT command
3. WiFi SMD Module – CC3000
The CC3000 from TI (Texas Instruments) is a self-contained wireless network processor that makes incorporating internet connectivity into your project simple. Instead of the more standard UART communication method, the CC3000 module utilizes an SPI interface allowing you, the user, to control the flow of data as you please. What makes the CC3000 unique is its ability to associate to a WiFi access point using a cell phone app in the Texas Instruments process called SmartConfig. This is a great module if you need to add wireless networking to your project!
* The CC3000 is an IEEE 802.11 b/g compliant WiFi module
* embedded IPv4 TCP/IP stack with an SPI host interface at 16MHz.
* 2.9V – 4.8V with current rating of 92mA
* connecting to WEP, WPA/WPA2 WiFi security Modes
4. pcDuino – WiFi Dongle
Want to free your pcDuino from the oppression of wired networking? This USB Wifi dongle has been tested to work with the pcDuino, simply plug it into the USB port and you’re ready to connect to a nearby wireless network!
5. WizFi220 -Ultra Low Power Serial-to-WiFi Module with Power Amplifier
The modules support data rates up to 11 Mbps, and are compliant with 802.11b. The WizFi210/220 modules provide customers the means to evaluate the capabilities of a ultra-low power wireless system–on–a-chip and Serial to Wi -Fi embedded software for Wi-Fi networks. The Serial to Wi-Fi embedded software allows devices and appliance manufacturers to easily add Wi-Fi capabilities to their products with minor impact on the host microcontroller firmware. The WizFi210/220 provides all the hardware and software necessary to quickly set up a serial (UART) link to a PC or external microcontroller.
