This is a very cheap Arduino Due Clone. Unfortunately my board do not work out of the box. After some research i find out, that in the position of C20, an 0 ohm resistor was mounted instead of a 10 nf capacitor, and a second capacitor (C29) was soldered only on one side. The problem is easy detectable: There is a short between MASTER-RESET and 3.3 Volt. You may see the following problems: -- You can download a sketch, but it do not start. You can start the sketch by pressing reset. -- If a sketch is running, you get the message, that no board is responding on the interface. Again, pressing the reset button help. As the reset button short the 3.3 volt supply without the modification, the lifetime of the reset button is very limited. ==> After fixing this problems, the board works like an original Arduino Due board. I think, this is a good product, and i will reorder another one.
