Arduino Mega Price in BD
First, I have to mention that-, this is the low-cost Chinese version of Arduino Mega 2560 R3 from China with the same feature, pinout diagram, and board size.
But, if you are only the quality concern people, then please check the genuine version of Arduino Mega 2560 R3 from SparkFun, USA. This high-quality PCB Board and all of the genuine components give you a quality performance.
The Arduino mega price in bd of a Chinese version is about 4 to 5 times lower than that of the genuine copy.
