Be forewarned that these look like an Arduino, work like an Arduino, smell like an Arduino, but are NOT Arduinos.
....and they don't cost like Arduinos either.
These are perfect for students/beginners on a budget, who can incorrectly wire or power an Arduino or those who want to put Arduinos to the test.. fatigue test that is. These are perfect for "rainy days", also quite literally.
These are better, much better than Made in India clones, but certainly not the real deal.
We got these cause many students asked for these, many compared our Arduino costs with chinduinos elsewhere and said we were still not the cheapest in India, and many suspected that we are selling chinduinos thus were the cheapest around. So we decided to put these side by side for our discerning customers to see and compare.
