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.
Very pleased with this product. Despite not being a branded Arduino, it is a great and very affordable substitute, and works exactly as required and is indistinguishable from Arduino Megas, despite being less than a third of the price. Came neatly arrived in a box and anti-static bag, so it would not be damaged in the delivery, and came with a USB cable that seems to function as required.
It seems to be a very well made third party implementation of the open source Arduino Mega board architecture. Nothing at all peculiar about it when I used it for an Arduino clock project. And it's stocked in Australia at a very reasonable price.
I had low expectations for the price these were going for, but was pleasantly surprised when I received mine. The boards are well built, nice silkscreening, no solder defects on the 4 boards I got. Everything works just as well as an official Arduino. Of course, you're not supporting the Arduino community when you purchase these, so maybe buy one of those as well... Otherwise, I will definitely be buying more of these (and their nano version as well -- just as well built).
