Cubieboard2 Dual card

General Details

Cubieboard2 Dual Card

Cubieboard2-Dual card version, CB2-2Card for short, is the low cost edition of Cubieboard2. Compared with cubieboard2, the only difference is the storage subsystem. Cubieboard2 has 4GB NAND Flash on board but replaced with a micro SD card slot in the Dual card version. It is open source hardware very suit for developers, geeks, makers and some other research workers. The CB2-2Card product is not only cost cutting, but also has some innovations in usage aspects. At least, there are three advantages in comparison with Cubieboard2. The first one is CB2-2Card has larger storage capacity potential. Since CB2-2Card has 2 micro SD card slots on the board, so that you can get more than 64GB storage capacity (32GB boot card 32 GB data card) without connecting the HDD.

The second advantage is more flexible usage against Cubieboard2. Because CB2-2Card has two card slots, the one in the top side is used for data storage, and the one in the bottom side can be used for system storage. So you can change your operating system very easily, even not need to reflash the Nand Flash. If you have more TF cards on hand, you can seamlessly try more operating systems.

The third advantage is more open. As you know, NAND flash driver is most important bits of intellectual property for a commercial company like A20 main chipset vendor. This achievement researched and practiced by several generation chips will not easily open to publics. So that Cubieboard can only choose to work around this problem. We think system program running in SD card is the best choice for study and research works.
