Install Massduino support package

Inorder to use Massduino UNO Pro , you need to download massduino support package from below link:


         After you download and unzip the file , you will got two folder:

Find the directory that suits your Arduino IDE version , copy to target directory . Here is the default sketchbook directory for most popluar system:

         > Windows: C:\Users\<Username>\Documents\Arduino

         > Mac OSX: /Users/user/Documents/Arduino

         > LINUX: /home/<Username>/sketchbook


         And then restart the Arduino IDE , you will see the device appear in the menu :

tools - > board - > Massduino Ev board -> MD-3248P-LQFT48

         Then , you can start to play with Uno Pro.
