產品簡介
本Wifi擴展板已升級到V2.2。疊加在主控板上，用於拓展wifi功能。具備Arduino下使用教程，降低wifi設備使用門檻。
超低功耗：這款擴展板採用Wizfi210模塊，可以利用動態電源管理達到低功耗(待機：34.0μA；接收：124mA；輸出：126mA)。另外，它還可 以設置待機模式（即當產品需要長期啟動，但不需要長期運行)。
TTL橋接：本款基於WizFi210芯片，擴展板提供TTL電平串口到IEEE802.11b/g/n無線通信的橋接。通過Wizfi210，任何具有TTL串口的設備都可以很容易地建立起無線網絡，實現遠程管理和控制。wizfi210內部集成多種通信協議及其加密算法。
兼容IEEE802.11n：它是IEEE最新批准的無線傳輸標準協議，具備更高傳輸速度，更廣網絡覆蓋，更強兼容性，更加安全的特點。目前許多無線電子設備廠商已經在大量產品中應用這一標準。
注意：本擴展板不兼容Arduino的SPI庫，只是提供SPI接口。另外本擴展板可能與部分Xirrus路由器不兼容。

DFRobot is very proud to release this first 802 b/g/n wifi shield in the Arduino market. The arduino shield uses WizFi210 which is a low power-consuming WIFI module which is applied with dynamic power management technology. When the WIFI module needs to be on but not work, it can be set to Standby mode a low power mode, and the module just needs to be woken up when it has to work.
The WIFI wireless module is based on WizFi210. It provides the bridging from TTL serial port communication to IEEE802.11b/g/n wireless communication. So any device with TTL serial ports can easily be connected with this WIFI module and controlled and managed remotely through a wireless network. Different kinds of communication protocols and encryption algorithms are integrated with the module. The Arduino architecture enables you to easily integrate this module into any Arduino based project.
