    Hardware:
    
      Allwinner H3 upto 1.2GHz
      512MB DDR3 RAM
      8GB on-board eMMC - mountable, can be used as boot with custom boot.scr
      microSD-card slot
      WiFi 802.11n (AP6212A) - working
      Bluetooth (AP6212A) - not working for now
      Micro-USB OTG + 2*USB headers
      UART 3.3V - working
      GPIO/I2C/SPI 2.54mm headers
    
    Standard sunxi SD-card installation procedure - copy image to SD card,
    insert in into slot and boot. First time you will need UART adapter to
    enable on-board wireless (or just build custom image with enabled WiFi).
    
    To boot from eMMC:
    
      - boot from SD
      - copy SD image to emmc (dd bs=... if=.... of=/dev/mmcblk2)
      - mount eMMC boot partition and replace boot script on it
      - unmount, reboot
    
    To use i2c, spi and more uarts - replace dtb on boot partition with
    fixed one (use dtc or fdt-tools).
