It has numerous development environments. You can go to the official website of Anxin to obtain resources. We can also use the Arduino IDE development environment because it is very simple. Below, we will use it as an example to illustrate its usage. The Arduino IDE software can be downloaded and installed using the Baidu installation method, which is not difficult.\u003c\/p\u003e\n\u003cp\u003e1.

Click to open the serial port monitor to check the WiFi connection status. If WiFi is not connected, the \"point number\" will be displayed. If WiFi is connected, the WiFi name and IP address will be displayed. The above is the usage method of the WiFi module in the Arduino development environment.\u003c\/p\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cp\u003e\u003cstrong\u003einventory\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e1X module\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/S9181bce8994c478a992141652a029740Q.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/Sa402f55ebb95431f900795fa74e8dba8x.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/S094271e8e56a44aa811848d1625249edl.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/S7de9f441a84a4cd581581e40c8272381e.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/Sbacd14bae13440378a54dd12c0ce6b81x.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/Sc0ed536bdbce48bf907aff2b7a181912q.jpg\" slate-data-type=\"image\"\u003e\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/div\u003e\u003c\/div\u003e\u003c\/div\u003e\u003c\/div\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Yoeruyo","offers":[{"title":"type-c 1pcs","offer_id":55506047664427,"sku":"14:29#type-c 1pcs","price":15.24,"currency_code":"USD","in_stock":true},{"title":"3pcs","offer_id":55506047697195,"sku":"14:202693815#3pcs","price":36.28,"currency_code":"USD","in_stock":true},{"title":"1pcs","offer_id":55506047729963,"sku":"14:1202#1pcs","price":13.68,"currency_code":"USD","in_stock":true},{"title":"2pcs","offer_id":55506047762731,"sku":"14:350852#2pcs","price":24.48,"currency_code":"USD","in_stock":true},{"title":"10pcs","offer_id":55506047795499,"sku":"14:200004890#10pcs","price":129.8,"currency_code":"USD","in_stock":true},{"title":"type-c 3pcs","offer_id":55506047828267,"sku":"14:1052#type-c 3pcs","price":35.56,"currency_code":"USD","in_stock":true},{"title":"type-c 10pcs","offer_id":55506047861035,"sku":"14:203192889#type-c 10pcs","price":136.08,"currency_code":"USD","in_stock":true},{"title":"type-c 2pcs","offer_id":55506047893803,"sku":"14:203322814#type-c 2pcs","price":25.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1000\/5744\/8747\/files\/S2760e8cf66f74c8c80b6dd7f4fee11ebQ.webp?v=1788926780","url":"https:\/\/yoeruyo.com\/products\/nodemcu-v3-esp8266-esp-12e-wifi-development-board-ch340g-square-blackboard-soldering-pin-micro-usb-interface","provider":"Yoeruyo","version":"1.0","type":"link"}
