XBee? Wifi

概述

增強版XBee® Wi-Fi嵌入式模塊。該低功率模塊采用流行的XBee形狀因數(shù)，能夠?qū)崿F(xiàn)串口轉(zhuǎn)Wi-Fi網(wǎng)絡(luò)功能，現(xiàn)在也具備了本地iDigi設(shè)備云集成、軟接入點(AP)接口和Wi-Fi保護(hù)設(shè)置(WPS)功能，非常便于進(jìn)行設(shè)備配置和維護(hù)。
迪進(jìn)國際公司的營銷高級副總裁Larry Kraft說：“由于其使用方便，形狀因數(shù)非常通用，并且具有本地iDigi設(shè)備云連接能力，新一代的XBee Wi-Fi產(chǎn)品能夠急劇加速Wi-Fi技術(shù)在連接機器方面的發(fā)展。利用本地iDigi設(shè)備云連接能力以及XBee產(chǎn)品的強大功能和簡便特性，即可極其容易地構(gòu)建遠(yuǎn)程支持的連接設(shè)備?！?

利用本地iDigi設(shè)備云連接能力，在快速創(chuàng)建或集成應(yīng)用時可以獲得設(shè)備的數(shù)據(jù)，此外還能夠進(jìn)行遠(yuǎn)程配置和下載固件。由于具有軟AP接口，XBee Wi-Fi模塊也能作為接入點。這樣用戶就能夠連接和配置一些(比較特殊的)設(shè)備(例如恒溫器、磅秤等);這些設(shè)備一般沒有類似于筆記本電腦(或智能手機)的液晶顯示屏(或鍵盤)接口。利用Wi-Fi保護(hù)設(shè)置功能，通過使用簡單的按鈕方法，就可以把XBee Wi-Fi模塊連接到網(wǎng)絡(luò)。

該XBee Wi-Fi模塊提供安全的802.11 b/g/n聯(lián)網(wǎng)功能，非常適用于工業(yè)監(jiān)控、資產(chǎn)跟蹤、家居自動化和油罐監(jiān)控。該模塊具備UART及串行外設(shè)接口(SPI)，能夠優(yōu)化與嵌入式微控制器的集成。該XBee Wi-Fi模塊具有通孔及表面安裝(SMT)規(guī)格，為設(shè)計產(chǎn)品提供極大的靈活性，從而降低開發(fā)成本和縮短上市時間。
1. 統(tǒng)一XBee封裝，允許OEM在同一接口選用不同無線協(xié)議；
2. 支持SPI和Uart串行接口；
3. 天線接口包含RPSMA，PCB，U.FL，Whip
4. 支持低功耗操作，睡眠狀況下，電流消耗低于2uA；
5. 802.11n支持高達(dá)65Mbps的數(shù)據(jù)率；
