Display – 9″ capacitive touch screen (800 x 480 pixels, 5 points touch). Storage – 8GB NAND FLASH + microSD card slot (Up to 32GB). SoC – AllWinner A33 quad core Cortex A7 processor 1.3 GHz (Overclocked to 1.5GHz?) with Mali-400MP2 GPU. Let’s check the specs of one of the no-name 9″ tablets currently available: All models currently listed feature 9″ to 10″ displays, so it’s safe to expect 7″ tablets to be close to $50. Tablets based on the new processor are now available for sale, and just as low as $60 including shipping on Aliexpress. The build image works on several of my A33 tablets, but gets stuck on the loading screen on some others.AllWinner A33 is a new quad core Cortex A7 processor pin-to-pin compatible will AllWinner A23 dual core processor, that costs less than $5 with the power management IC (AXP223). You may need to replace the 圓 sys_config.fex with an appropriate fex for your A33 tablet. I was able to succesfully build the SDK on Ubuntu 12.04 (after installing dependencies and java) and burn it to an SDCard using PhoenixCard and have it run on an A33 tablet. You will need to install the Baidu Yun Guanjia download manager in order to download the files. A33 Development Materials (Sources: )Ī33 will officially support Android 4.4 and above from AllWinner, so no official multi-OS support like some other higher-end AllWinner SoCs.īelow are links on pan baidu for the original A33 SDK.
