Columbus A31

Specification

     

    Size: 235*187*68mm

    Input Power:12V/3A

    Resolution:2048*1536


  • Columbus development kit is released by WITS which based on Allwinner A31.Columbus shows that powerful functions of A31,various Interfaces and extremely stable platform.It can be development and test platform of tablets, advertising machine,education, security,smart TV,IBMS, industrial control, medical, car media and mobile phone etc. ,shorten the development cycle of the companies’ products.

     

    A31 is a quad-core mobile application processor provided by Allwinner Technology. A31 uses quad-core CPU structure of Cortex-A7, equipped with POWER VR SGX544 MP2 GPU and has 8 Presentation Engine and can provide 4Kx2K video decoding and output at the same time.

     

    In addition, equipped with dual-channel 64-bit DDR3 and dual-channel 16-bit NAND Flash. A31 can not only promote the reading and writing speed of the random-access memory, but solve the bandwidth problem. Moreover, A31 have perfect power consumption management system and equipped with a smart power management chip named AXP221 which is developed independent achieving the dynamic power management and a more battery life.

    Point Properties of A31 processor

    ● Game

    In the stage of A31 four-core eight-display, the picture quality of the games has a great promotion:It has lower sawtooth and the frames become more smooth. At the same time, the compatibility is promoted a lot. The compatibility will be over 95% if you choose the same series of GPU of the Apple.

    ● Website

    The website can offer a suspension video and a faster loading speed. If the bandwidth is fast enough, the mainstream web loading time can lower than 5 seconds.

    ● Camera

    A31 has 4 lanes MIPI CSI connector and can offer a camera with 12 million pixels, videotape with 1080P@60fps, and it also can do face detection, pan-shot, auto-focusing and camera for 3D, etc.

    ● Memory

    A31 can offer 16-bit dual-channel NAND, the reading and writing speed can promote to 100%.

    ● Low Power Consumption

    The endurance of A31 can be promoted to over 20%: supports the standby time to be over 30days , music player time to be over 100 hours, video playing time to be over 10 hours and the web searching time to be over 8 hours.

    ● Screen

    A31 supports retinal screen, the resolution ratio of which can reach 2048x1536.
