The processor used in OpenELAB EASY plug control board V2.0 is ATmega328. It has 5 single Digital ports labeled D5 to D9 (of which 3 can be used as PWM outputs), 1 dual-digital interface (D3-D4), 4 analog inputs (A0-A3), a Joystick interface (D2-A6-A7), a SPI communication, a serial port communication and an IIC communication interface. Also with a USB connection, a power jack, two ICSP headers and a reset button. It breaks out the IO ports with RJ11 6P6C plug. Simply connect it to a computer with a USB cable or power it via a DC jack to get started. For convenience of wire connection, we simplify the pins GND and VCC into each plug, so you only need one RJ11 6P6C connector wire to connect an external sensor or module, no need to separately connect the VCC and GND. So don't worry that the wrong wiring will damage the external products.
PCB Dimensions: 100mm x 65mm x 18mm
Weight: 55.5g
Here is an explanation of what every element and interface of the board does:
When you get the board, first you should install the Arduino software and driver. We usually use the Windows software Arduino 1.5.6 version. You can download it from the link below: https://www.arduino.cc/en/Main/OldSoftwareReleases#1.5.x Or you can browse the ARDUINO website to download the latest version from this link, https://www.arduino.cc, pop up the following interface.
Then click the SOFTWARE on the browse bar, you will have two options ONLINE TOOLS and DOWNLOADS.
Click DOWNLOADS, it will appear the latest software version of ARDUINO 1.8.5 shown as below.
In this software page, on the right side you can see the version of development software for different operating systems. ARDUINO has a powerful compatibility. You should download the software that is compatible with the operating system of your computer. We will take WINDOWS system as an example here. There are also two options under Windows system, one is installed version, the other is non-installed version. For simple installed version, first click Windows Installer, you will get the following page.
This way you just need to click JUST DOWNLOAD, then click the downloaded file to install it. For non-installed version, first click Windows ZIP file, you will also get the pop-up interface as the above figure. Click JUST DOWNLOAD, and when the ZIP file is downloaded well to your computer, you can directly unzip the file and click the icon of ARDUINO software to start it.
Installing Arduino (Windows)
Install Arduino with the exe. Installation package downloaded well.
Click“I Agree”to see the following interface.
Click “Next”. Pop up the interface below.
You can press Browse… to choose an installation path or directly type in the directory you want. Then click “Install” to initiate installation.
Wait for the installing process, if appear the interface of Window Security, just continue to click Install to finish the installation.
Introduction for Arduino IDE Toolbar
Installing Driver
It will then be prompted to either “Search Automatically for updated driversoftware” or “Browse my computer for driver software”. Shown as below. In this page, select “Browse my computer for driver software”.
After that, select the option to browseand navigate to the “drivers” folder of Arduino installation.
Click “Next” and you may get a security warning, if so, allow the software to be installed. Shown as below.
Once the software has been installed, you will get a confirmation message. Installation completed, click “Close”.
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.
Connect the board to your computer using the USB cable. The power LED should go on.
Open the Arduino IDE, you’ll need to click the “Tools”, then select the Board that corresponds to your Arduino.
Select the serial device of the Arduino board from the Tools | Serial Port menu. Note: to avoid errors, the COM Port should keep the same as the Ports shown on Device Manager.
Below is an example code for displaying the Hello World! Copy and paste the code to the Arduino environment IDE.
After that, click the serial monitor button to open the serial monitor.
Then set the baud rate as 9600, enter an “R” and click Send, you should see the RX led on the board blink once, and then D13 led blink once, finally "Hello World!" is showed on the monitor, the TX led blink once. Congrats!

Double-click the icon of Arduino software downloaded well, you will get the interface shown below. (Note: if the Arduino software loads in the wrong language, you can change it in the preferences dialog. See the environment page for details.)
Next, we will introduce the driver installation of board. The driver installation may have slight differences in different computer systems. So in the following let’s move on to the driver installation in the WIN 7 system. The Arduino folder contains both the Arduino program itself and the drivers that allow the Arduino to be connected to your computer by a USB cable. Before we launch the Arduino software, you are going to install the USB drivers. Plug one end of your USB cable into the board and the other into a USB socket on your computer. When you connect the board to your computer at the first time, right click the icon of your “Computer” —>for “Properties”—> click the “Device manager”, under “Other Devices”, you should see an icon for “Unknown device” with a little yellow warning triangle next to it. This is your Arduino. Then right-click on the device and select the top menu option (Update Driver Software...) shown as the figure below..
