Ranked in these QuestionsQuestion Ranking
Pro Extremely cheap for what it promises
The Orange Pi PC is extremely cheap, especially compared to the SBCs it competes against.
Pro Great value for the price
Great little linux box for the price
Pro Supports almost all OSes supported by Raspberry
Orange Pi supports Raspbian, Ubuntu, Android and many more operating systems. It claims to support all OSes supported by Raspberry Pi and it seems to be true most of the time.
Con First Party OS support is practically non-existent
Con no wifi
Con Has some thermal throttling issues
The Orange Pi can get pretty hot, up to the point where it needs to shut down cores to keep it from locking up.
Con Has problems with slow microSD cards
Anything less than a class 10 TF/microSD card will probably not work with the Orange PI. Since the testing and production of the Orange Pi was rushed massively, as a result it cannot step down to be more compatible with slower SD cards. Although it should be mentioned that this is not that much of a problem since you can get class 10 microSD cards for pretty cheap nowadays.
Con No video connector natively
Must use RPIO equivalent to wire any video.
