由外觀看起來chip是ESP8266MOD
接上USB後，因為CH340的USB chip, win10預設沒driver
直接選自動更新就可以取得driver，win10就是這一點好!
打開com port，發現下AT都沒反應 (115200)
按板子上的reset鍵發現是有資料出來的
如下：

後來把結尾字元改為"\r\n"就正常了

參考這邊的版本指令：
http://www.electrodragon.com/w/ESP8266_AT-Command_firmware
這邊有不少資源，但還未確認是否可用，真的很猛，連怎麼在WiFi的chip跑RTOS都有寫手冊

AT command手冊
http://www.espressif.com/sites/default/files/documentation/4a-esp8266_at_instruction_set_cn.pdf
看手冊使用了幾個指令都OK，代表買回來的東西是可以用的，GOOD!
