@PawelK The Banana Pi was this SBC from somewhere in China and the details of it back in those days were rather fuzzy.
I got an A20 All winner dual core SoC with PMIC, jst battery connector, sata port and a full gigabyte of ram for about twice the price of a Raspberry Pi. It had the newer Arch so I still can use regular Linux on it to this day.
Dealing with it back in 2014? It was a massive disappointment. CHIP hadn't come along with the Mali open source and that wouldn't happen for a while longer. I liked to go with Allwinner chips because I associated them with AXP pmics which would allow one to hook up a 3.7v lion battery and it would manage charge and discharge.
