Description
Seeeduino Cloud is a microcontroller board based on Dragino WiFi IoT module HE and ATmega32u4. HE is a high performance, low cost 150M, 2.4G WiFi module which means “core” in Chinese and with an Open Source OpenWrt system inside. Seeeduino Cloud is also an Arduino compatible board, 100% compatible with Grove, shield and IDEs(Arduino IDE 1.5.3 and later). Except for the normal interface of Arduino, Seeeduino Cloud has built-in Ethernet and WiFi support, a USB-A port which makes it very suitable for those prototype design that needs network connection and mass storage. It is also a good idea to make Seeeduino Cloud to an IoT gateway.

介紹 ：
Seeeduino Cloud是基於Dragino無線物聯網模塊的微控制器板HE和ATmega32u4。他是一個高性能，低成本的150M，2.4G WiFi模塊，這意味著“核心”的中國和一個開源的OpenWrt系統內部。 Seeeduino雲也是一個Arduino兼容板，100％兼容格魯夫，盾牌和集成開發環境（IDE Arduino的1.5.3或更高版本）。除了Arduino的正常界面，Seeeduino雲還內置以太網和無線網絡支持，USB-A接口，這使得它非常適合那些原型設計需要的網絡連接和海量存儲。這也是一個好主意，使Seeeduino雲是一個物聯網網關。
