Connect your Arduino to the Internet with this fine new FCC-certified WiFi module from Atmel. This 802.11bgn-capable WiFi module is the best new thing for networking your devices, with SSL support and rock solid performance - running Adafruit's adafruit.io MQTT demo for a full weekend straight with no hiccups (it would have run longer but Adafruit had to go to work, so they unplugged it). Adafruit like these so much, they've completely replaced the CC3000 module on all Adafruit's projects.
The Adafruit ATWINC1500 WiFi Breakout uses SPI to communicate, so with about 6 wires, you can get your wired up and ready to go. Right now the Atmel-supplied library works great with Arduino Zero, and seems to work OK on Uno but may not work on other Arduinos. You can clock it as fast as 12MHz for speedy, reliable packet streaming. And scanning/connecting to networks is very fast, a few seconds.
This module works with 802.11b, g, or n networks & supports WEP, WPA and WPA2 encryption. You can use it in Soft AP mode to create an ad-hoc network. For secure client connections, there is TLS 1.2 support in firmware 19.4.4!
Since this is Adafruit's new favoritest SPI-protocol WiFi module Adafruit have decided to make a little breakout for it. The breakout comes with level shifting on all the input pins so you can use it with 3V or 5V logic. A 3.3V voltage regulator that can handle the 300mA spikes lets you power from 3-5.5VDC. There's also 3 LEDs that you can control over the SPI interface (part of the library code) or you can have controlled by the Arduino library. They'll light up when connected to an SSID, or transmitting data.
Note: This version does not come with an onboard antenna, you will need a uFL connector antenna such as 2.4GHz Mini Flexible WiFi Antenna - not included! Adafruit have a version with on-board antenna as well
