Original Cubieboard2 dual core A20 arm cortex-a7 development board, surpassing raspberry pie and pcduino

Replacing the Nand Flash on board of Cubieboard2 with a TF card slot has made some significant breakthroughs. The "Cubieboard2 Dual Card Edition" retains the vast majority of the traditional excellent genes of Cubieboard2, and has the following three undeniable advantages compared to Cubieboard2 or other open source hardware Advantage 1: The pricing of the "Cubieboard2 Dual Card Edition" will be comparable to the latest version of Raspberry Pi (UK), with a sales price of 238 RMB. We want domestic enthusiasts to spend less, but get more, and use it more effectively. Advantage 2: More flexible gameplay. The UK Raspberry Pie does not have onboard Flash memory, while Cubieboard2 has 4GB of Flash memory. Throughout the operation and maintenance process of Cubieboard2, we have found that enthusiasts have a plethora of ideas. Only by providing them with a more flexible hardware component can their thinking soar and soar. Equipped with the excellent system boot mechanism of the Quanzhi A20 main chip, the "Cubieboard 2 Dual Card Edition" easily implements a dual card solution, which greatly enhances playability: the operating system is easily replaceable. Cubieboard, as a well-known open-source hardware with high cost-effectiveness, is supported by numerous operating systems both domestically and internationally, and not only by personal maintenance, but also by well-known distribution companies. Faced with so many operating systems, do you want to experience one by one, but there is also one that you love the most and can't bear to brush it off? The 'Cubieboard2 Dual Card Edition' can solve your problem, as long as you prepare 2 TF cards, one of which cannot be easily swiped to your liking, and the other one is used for tasting and experiencing one by one. After the experience is completed, plug in the one you like and keep all the software and system configurations installed unchanged. Another card slot can be used to insert data cards and store your own small documents, photos, movies... It not only has system flexibility but also maintains content, which is in line with the main theme of today's cloud age. The memory capacity has further improved. Cubieboard products have been breaking through the problem of capacity. In the era of big data, without storage capacity as a hardware foundation, it is impossible to complete any software operations. Therefore, Cubieboard products are committed to supporting hard drives on such mini PCs. With the release of the Cubieboard2 dual card version, products can achieve over 100G of storage capacity without expanding the hard drive, further breaking through while meeting mobility requirements. Advantage 3: The software has a higher degree of open source. This time, the launch of the "Cubieboard2 Dual Card Edition" is mainly aimed at abandoning Nand Flash, a hardware form controlled by large foreign companies, and replacing it with TF with interface standards. Due to the closed nature of the Nand Flash driver, it brings many compilation error issues, version incompatibility issues, and even system code drop issues to Cubeboard players. At present, the software ecosystem of Cubieboard based on card operation has formed, and more attention will be paid to the management of source code and document tutorials in the future.
