To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
This "Arduino Mega 2560" is NOT ready out of the box for instant connectivity to the IDE software. Tried all sorts of solutions to get the board to talk to my PC to no success. Searched the internet for all types of solutions from simple patch cord changes, to looking for the "driver" that should not have to be installed. I even uploaded the latest rev. of Arduino IDE... no success. Other arduino platforms work just fine. The problem is in the board and it is not prepped to talk to the IDE as it states. Purchased a different brand and it came right up. This is going back to the seller.
Addendum: I have had pretty good service for this device as long as I kept it plugged into 5V power source. Recently, I had to plug it into a 12v power source (actually 11.2v) through the VIN port (something I have to do on almost all my projects) and found that when I did this, the 5v rail was pushing out almost 8v. This fried a couple of stepper motor controllers. Upshot: If your doing minor things with this plugged into a well regulated power source through the barrel jack, no problem. But if you decide to do something more serious, DO NOT count on the 5v rail to be 5v.
I did not have this issue with the uno from keyStudio, so I guess it's just the Mega's.
