SBC: please don't use Allwinner CPUs
Hi,
please don't use a Allwinner CPU, because they have a lot of GPL violations, also the Linux kernel support is awful (http://linux-sunxi.org/GPL_Violations).
I would recommend a Beaglebone Black(BBB) or a Bealgebone Pocket (or OSD335x, ist a System in a Package, based on BBB)
