From the project
A small and easy to use miner for kryptokrona
The board features 64-bit 1.5GHz Quad-Core Cortex-A53 Allwinner H616 SOC, up to 8 Gbit (1 GB) of FBGA-96 16x DDR3 RAM, Micro SD slot, USB HS Host connector and integrated CP2102 USB-UART converter. 4 layers; 3,5/3,5 mil; 0,35/0,15 via, 80u prepreg. There are KiCad project, Gerber files and PDF avaliable.
For this guide we will be using armbian, since its lightweight and has support for our processor.
