arduinoethernet w5100網(wǎng)絡(luò)擴(kuò)展模塊，可以使arduino成為簡(jiǎn)單的web服務(wù)器或者通過(guò)網(wǎng)絡(luò)控制讀寫(xiě)arduino的數(shù)字和模擬接口等網(wǎng)絡(luò)應(yīng)用。可直接使用ide中的ethernet庫(kù)文件便可實(shí)現(xiàn)一個(gè)簡(jiǎn)單web服務(wù)器。
同時(shí)該版本的支持minisd卡（tf卡）讀寫(xiě)
該擴(kuò)展板采用了可堆疊的設(shè)計(jì)，可直接插到arduino上，同時(shí)我們的其他擴(kuò)展板也可以插上去。
