Seeed Wifi Shield V2.0 Arduino/ Seeeduino 無線網路 wifi 擴展板

商品說明

WiFi Shield V2.0 擴展板配置RN171 TCP/IP無線模組，可讓Arduino / Seeeduino連接高達802.11b / g的無線網絡。RN171無線模組支持TCP，UDP，FTP和HTTP通信協議，可以滿足大多數無線和物聯網（IoT）網絡項目的需求，例如智能家居網絡，機器人控件和個人氣象站。
屏蔽層覆蓋範圍廣，並通過新的穩定的車載天線傳輸強信號。Arduino的默認通信協議是UART / Serial，您可以通過我們合併的兩根跳線選擇用於RX和TX的數字引腳（D0至D7）。屏蔽層還具有兩個I2C和串行的Grove連接器，以使其可以與任何其他Groves一起插入。

Wifi Shield V2.0 技術補充（英文）

以下為原廠英文技術說明，提供使用者參考。

Featured with RN171 TCP/IP module, the WiFi shield allows your Arduino/Seeeduino to connect wireless networks up to 802.11b/g. The RN171 module supports TCP, UDP, FTP and HTTP communication protocols, which meet the needs of most wireless and Internet of Things (IoT) network projects, such as smart home networks, robots controls and personal weather stations.

The shield covers a wide range and transmit strong signals with the newly, stable on-board antenna. The default communication protocol with the Arduino is UART/Serial, and you can select which digital pins (D0 to D7) to use for RX and TX with the two jumper rows we’ve incorporated. The shield also has two Grove connectors of I2C and Serial to make it can be plugged with any other Groves.

The shield is well documented with demos and you can check the User Manual here online.

Features

• Various demos with step-by-step tutorials
• Low power consumption
