As we know that arduino is an open source and hardware . Briefly we can say that they arduino allow people to copy their design freely but not their arduino trademark or name . This is to allow the open source community to grow bigger .
So how to differentiate which one is Original , Compatible , fake or clone ? First we try define it first .
Original : Come from arduino official . The quality is guarantee from arduino . Standard price .That all . How to know it come from arduino official , we will elaborate that later .
Compatible : Come from various company and various country . The quality is gurantee from their own manufacturer , not from arduino official . Exactly , may have the same shape and functionality as arduino , but they are not using the name arduino . No arduino name print on the board . Some of it may have different colour, shape and design but still have the same functionality as arduino . Lastly may have a cheaper price than original one .
Fake or clone : Come from various company and various country . The quality is gurantee from their own manufacturer , not from arduino official . Exactly the same shape and functionality as arduino and they are using the name arduino without arduino permission . Arduino name print on the board without arduino official permission .
How to know it is Original ?
First, it come without USB and inside seal arduino box . That all . I never find yet the compatible , fake or clone that come with seal arduino box .
One more thing is you may get the genuino brand for outside united state . This may not fully implement , because official distributor in my country still sell the arduino printed one .
How the Compatible looks like ?
May have the same design and functionality as the original one but you may notice that there is likely no arduino name printed on it .
How the fake or clone looks like ?
