Although there have been many development boards before it, like the Arduino and BeagleBoard, the Raspberry Pi undoubtedly started a new trend of offering those same benefits with a more open hardware and, perhaps more importantly, a more affordable price tag. That has spurred a host of other boards, clones even, that try to repeat the magic of the RPi. Like this awesomely (not) named Orange Pi PC, from the makers of the Orange Pi, 1 and 2. They're advantage over the RPi? 20 bucks less.
