In product description there was not mentioned about lack of software support, no dual gigabit ethernet(in single port mode 90Mbps, dual port mode max 10Mbps) , no real sata3 speed support(disk to disk performance was 14MBps of 2 ssd's), no full hdmi support, only work if using kernel for single ethernet card, no support for booting from emmc - every time boot hangs. Was using every possible way for achieve full speeds of interfaces but without success, seller communication also was very poor, didn't gave any answer to my question.
Item is interesting and could be useful but software & firmware support isn't really good enough. Some features on the board don't work with some of the OS images made by the company and some basics like support for bluetooth dongles don't work either. Plus a component blew within 3 weeks of purchase. Still, sinovoip had good customer service and were happy to refund.
