Main changes from the older version: 
Add two rows of the holes for the pins. So it can be connected with normal Dupont line. 
Add 3 rows of the holes for wiring. 
Testing!
We program & test all devices with LED blinking Program. 
Please make sure to connect the device to USB & test if the LED-"L" is blinking,
This shows the device is working perfectly (Don't modify program without completing this preliminary test).
