***本商品為研發實驗用的模組，無法隨插即用，“非成品"
須經專業背景人士（如：工程師、研究生、師生）
撰寫程式、燒錄、接線等二次加工後，才具備訊號傳輸功能。
並非直接插電後可直接使用之射頻模組，未經組裝無法使用
非屬電信管制射頻器材，購買前請詳閱商品說明。

範例：
#include
const char* ssid = "xxxxx"; // fill in here your router or wifi SSID
const char* password = "xxxxxx"; // fill in here your router or wifi password
#define RELAY 0 // relay connected to GPIO0
WiFiServer server(80);
void setup()
{
Serial.begin(115200); // must be same baudrate with the Serial Monitor
pinMode(RELAY,OUTPUT);

// Connect to WiFi network
