==Description==
This keyestudio ESP8266 WI-FI development board is based on the ESP8266-12FWIFI module developed by Ai-Thinker. <br>
The processor ESP8266 integrates the industry-leading Tensilica L106 ultra-low-power 32-bit micro MCU in a smaller package, with 16-bit Lite mode. The main frequency supports 80MHz and 160 MHz.<br>
It supports RTOS, integrated with Wi-Fi MAC/BB/RF/PA/LNA. Onboard comes with curved antenna.<br>
This development board is a standalone network controller, which can add networking function to those existing devices. <br>
When using, power the board and upload the program via a Micro USB port, and the current supply should be 2A.

==Detailed Using Method as follows==
===Step1| Install the Arduino IDE===
When programming the control board, first you should install the Arduino software and driver. <br>
You can download the different versions for different systems from the link below:  <br>
https://www.arduino.cc/en/Main/OldSoftwareReleases#1.5.x

<span style="color: red">'''Note: ''' </span> this control board is only compatible with Arduino 1.6.5 version or latest. <br>
In the following, we will download the Arduino 1.6.5 version. </span><br>
<br>[[Image:ks0389 Step1-1.png|600px|frameless]]<br>

In this Windows system page, there are two options. One is Windows version, the other is Windows Installer. <br>
For Windows Installer, you can download the installation file, this way you need to install the arduino IDE. 
<br>[[Image:ks0389 Step1-2.png|600px|frameless]]<br>

For simple Windows version, you can download the software directly, do not need to install, just directly use the software after unzip the file.
<br>[[Image:ks0389 Step1-3.png|600px|frameless]]<br>

Next, we click the Windows, pop up the interface as below.
<br>[[Image:KS0313-5.png|600px|frameless]]<br>

Click '''JUST DOWNLOAD'''. <br>
When the ZIP file is downloaded well to your computer, you can directly unzip the file. Open the Arduino-1.6.5-r5 folder, you should get it as follows.[[Image:ks0389 Step1-4.png|400px|frameless]]<br>
<br>[[Image:ks0389 Step1-5.png|600px|frameless]]<br>

Click the icon of ARDUINO software to open it. This is your Arduino.
<br>[[Image:ks0389 Step1-6.png|600px|frameless]]<br>
<br>

===Step2| Install the Driver===
The USB to serial port chip of this control board is '''CP2102-GMR'''. So you need to install the driver for the chip. <br>
You can click the driver package download link here.<br>
https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers

You can download the driver software for different systems.
<br>[[Image:ks0389 Step2-1.png|600px|frameless]]<br>

For example, download for Windows 7, you can get the driver package '''CP210x_Windows_Drivers.'''
<br>[[Image:ks0389 Step2-2.png|600px|frameless]]<br>

Unzip the package to install the driver. 
<br>[[Image:ks0389 Step2-3.png|600px|frameless]]<br>

Then double click '''CP210xVCPInstaller_x64''' to install the driver. Shown below.
<br>[[Image:ks0389 Step2-4.png|600px|frameless]]  [[Image:ks0389 Step2-5.png|600px|frameless]]  
<br>[[Image:ks0389 Step2-6.png|600px|frameless]] [[Image:ks0389 Step2-7.png|600px|frameless]]<br>

<br>
===Step3| Install the ESP8266 with Arduino===
Double-click the icon of Arduino software downloaded well, you will get the interface shown below.
<br>[[Image:Ks0313图片1.png|600px|frameless]]<br>
(<span style="color: red">'''Note: ''' </span> if the Arduino software loads in the wrong language, you can change it in the preferences dialog. See [https://www.arduino.cc/en/Guide/Environment-Languages the environment page] for details.)

<br>

Firstly, plug one end of your USB cable into the Keyestudio ESP8266 WI-FI module and the other into a USB socket on your computer. 
<br>[[Image:ks0389 Step3-3.png|600px|frameless]]<br>

Then open the Arduino IDE, click the “File” to select the “Preferences”.
<br>[[Image:ks0389 Step3-2.png|600px|frameless]]<br>

The pop-up interface is shown below. <br>
See the “Additional Boards Manager URLs”, copy and paste the link below: 
http://arduino.esp8266.com/stable/package_esp8266com_index.json

and then click OK.
<br>[[Image:ks0389 Step3-4.png|600px|frameless]]<br>

After that, click “Tools”, for “Board”, enter the Boards Manager, it will automatically download the relevant file. Shown below.
<br>[[Image:ks0389 Step3-5.png|600px|frameless]]<br>

Pop up the following window:
<br>[[Image:ks0389 Step3-6.png|600px|frameless]]<br>

Done downloading the relevant file, it will pop up the window below. <br>
Then enter the 8266 on the blank bar and click Install.
<br>[[Image:ks0389 Step3-7.png|600px|frameless]]  [[Image:ks0389 Step3-8.png|600px|frameless]]<br>

Installation completed, click Close, then click “Tools”, for “Board”, you should see the '''NodeMCU 1.0 (ESP-12E Module)'''. Shown below.
<br>[[Image:ks0389 Step3-9.png|600px|frameless]]<br>

<br>

===Step4| Add the Libraries===
Before upload the code to test your board, you should first add the library ESP8266WiFi into the libraries folder of Arduino-1.6.5-r5. <br>
You can click the link to download the library needed.<br>
https://drive.google.com/open?id=1_Y5lKCrDgY3AeovXZKorQ8FVk2olUOOL
<br>[[Image:ks0389 Step4-1.png|600px|frameless]]<br>

<span style="color: red">'''Note: ''' <br>
Before adding the library, you have opened the Arduino IDE. After add the library successfully, must restart the IDE, so the library can work. 

<br>
===Step5| Select the Board and Serial Port===
Open the Arduino IDE, you’ll need to click the “Tools”, then select the Board and the Serial Port.
<br>[[Image:ks0389 Step3-9.png|600px|frameless]]<br>

You can check out the Serial Port on your computer’s Device Manager.<br>
Select your proper COM Port. 
<br>[[Image:ks0389 Step5-1.png|600px|frameless]]  [[Image:ks0389 Step5-1.png|600px|frameless]]<br>

<br>
===Step6| Upload the Code===
Add well the libraries mentioned above, and select the proper Board and Port, you should upload the code to test the module. <br>
Below is an example code, you can copy and paste it on Arduino IDE. 
<pre>
/*
 *  This sketch demonstrates how to scan WiFi networks. 
 *  The API is almost the same as with the WiFi Shield library, 
 *  the most obvious difference being the different file you need to include:
 */
#include "ESP8266WiFi.h"

void setup() {
  Serial.begin(115200);

  // Set WiFi to station mode and disconnect from an AP if it was previously connected
  WiFi.mode(WIFI_STA);
  WiFi.disconnect();
  delay(100);

  Serial.println("Setup done");
}

void loop() {
  Serial.println("scan start");

  // WiFi.scanNetworks will return the number of networks found
  int n = WiFi.scanNetworks();
  Serial.println("scan done");
  if (n == 0)
    Serial.println("no networks found");
  else
  {
    Serial.print(n);
    Serial.println(" networks found");
    for (int i = 0; i < n; ++i)
    {
      // Print SSID and RSSI for each network found
      Serial.print(i + 1);
      Serial.print(": ");
      Serial.print(WiFi.SSID(i));
      Serial.print(" (");
      Serial.print(WiFi.RSSI(i));
      Serial.print(")");
      Serial.println((WiFi.encryptionType(i) == ENC_TYPE_NONE)?" ":"*");
      delay(10);
    }
  }
  Serial.println("");

  // Wait a bit before scanning again
  delay(5000);
}
</pre>

After copy and paste the code on IDE, click the compile button, if compiling successfully, the message "Done compiling." will appear in the status bar. 
<br>[[Image:ks0389 Step6-1.png|600px|frameless]]  [[Image:ks0389 Step6-2.png|600px|frameless]]<br>

Then click the “Upload” button, if the upload is successful, the message "Done uploading." will appear in the status bar.
<br>[[Image:ks0389 Step6-3.png|600px|frameless]]  [[Image:ks0389 Step6-4.png|600px|frameless]]<br>

<br>
===Step7| What Should You See===
Done uploading the code, open the serial monitor and set the baud rate to 115200, you should see all the WIFI information.
