Overview
This board enables Arduinos and other embedded devices to communicate with wireless networks via the 802.11 protocol.
The board has a microchip that implements the entire TCP/IP stack, so you don't have to implement it on your embedded device. The embedded device simply uses serial commands to control and interact with the chip. Think of it as a dumbed-down, physical API for wifi.
The chip has an 8-pin array on the underside. The pins here use 3.3 V logic, so it is important you use it with embedded devices that also use 3.3 V logic! Some embedded devices (such as the Arduino Uno) use 5 V logic. If you have a device using 5 V logic, you need a down-converter (also called a level shifter) to convert the 5 V logic signals to 3.3 V logic signals.
