Keyestudio ESP8266 WI-FI Board (Black and Eco-friendly)


Description

This keyestudio ESP8266 WI-FI development board is based on the ESP8266-12FWIFI module developed by Ai-Thinker.
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.
It supports RTOS, integrated with Wi-Fi MAC/BB/RF/PA/LNA. Onboard comes with curved antenna.
This development board is a standalone network controller, which can add networking function to those existing devices.
When using, power the board and upload the program via a Micro USB port, and the current supply should be 2A.

Detailed Using Methods are as follows:

Step1| Install the Arduino IDE

When programming the control board, first you should install the Arduinosoftware and driver.
You can download the different versions for different systems from the link below:
https://www.arduino.cc/en/Main/OldSoftwareReleases#1.5.x

NOTE: this control board is only compatible with Arduino 1.6.5 version or latest.
In the following, we will download the Arduino 1.6.5 version.

Ks0354-step1-1.png

In this Windows system page, there are two options. One is Windows version, the other is Windows Installer.
For Windows Installer, you can download the installation file, this way you need to install the arduino IDE.
Ks0354-step1-2.png

For simple Windows version, you can download the software directly, do not need to install, just directly use the software after unzip the file.
Ks0354-step1-3.png

Next, we click the Windows, pop up the interface as below.
Ks0354-step1-4.png

Click JUST DOWNLOAD.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.
Ks0354-step1-5.png

Ks0354-step1-6.png

Click the icon of ARDUINO software to open it. This is your Arduino.
Ks0354-step1-7.png


Step2| Installing the Driver

The USB to serial port chip of this control board is CH340G. So you need to install the driver for the chip. You can click the driver file here usb_ch341_3.1.2009.06 to download it.
In different systems, the driver installation is similar. Here we start to install the driver on the Win7 system.
Plug one end of your USB cable into the Keyestudio ESP8266 WI-FI board and the other into a USB socket on your computer.
When you connect the ESP8266 WI-FI board to your computer at the first time, right click your “Computer” —>for “Properties”—> click the “Device manager”, under Other devices, you should see the “USB2.0-Serial”.
Ks0354 driver 1.png

Then right-click on the device and select the top menu option (Update Driver Software...) shown as the figure below..
Ks0354 driver 2.png

Then it will be prompted to either “Search Automatically forupdated driversoftware” or “Browse my computer for driver software”. Shown as below. In this page, select “Browse my computer for driver software”.
Ks0354 driver 3.png

After that, select the option to browseand navigate to the “drivers” folder of usb-ch341 installation.
Ks0354 driver 4.png

Once the software has been installed, you will get a confirmation message. Installation completed, click “Close”.
Ks0354 driver 5.png

Up to now, the driver is installed well. Then you can right click “Computer” —>“Properties”—>“Device manager”, you should see the device as the figure shown below.

Step3| Installing the ESP8266 with Arduino

Double-click the icon of Arduino software downloaded well, you will get the interface shown below.
Ks0313图片1.png
(Note: if the Arduino software loads in the wrong language, you can change it in the preferences dialog. See the environment page for details.)
Ks0354-step1-7.png

The functions of each button on the Toolbar are listed below:
IDE.png

IDE 1.png Verify/Compile Check the code for errors
IDE 2.png Upload Upload the current Sketch to the Arduino
IDE 3.png New Create a new blank Sketch
IDE 4.png Open Show a list of Sketches
IDE 5.png Save Save the current Sketch
IDE 6.png Serial Monitor Display the serial data being sent from the Arduino

First, plug one end of your USB cable into the Keyestudio ESP8266 WI-FI board and the other into a USB socket on your computer.
图片2-ks0367.png

Then open the Arduino IDE, click the “File” to select the “Preferences”.
Ks0354-step3-1.png

The pop-up interface is shown below. See the “Additional Boards Manager URLs”, copy and paste the link: http://arduino.esp8266.com/stable/package_esp8266com_index.json and then click OK.
Ks0354-step3-2.png

After that, click “Tools”, for “Board”, enter theBoards Manager, it will automatically download the relevant file. Shown below.
Ks0354-step3-3.png

Below is the complete settings you should refer to:
Ks0354 Tools.png


Step6| Upload the Code

Add well all the libraries mentioned above, and select well the Board and Port, you should upload the code to test your board.
Below is an example code, you can copy and paste it on Arduino IDE. Or dowload the code here

/*
 *  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);
}


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. Shown below.
Ks0354 upload-3.png

Then click the “Upload” button, if the upload is successful, the message "Done uploading." will appear in the status bar.
Ks0354 upload-4.png


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.
