FriendlyELEC introduced a second version of NanoPC-T6 SBC.
The miniPCIe slot got removed and USB 2.0 configuration has changed.
There are two external accessible ports and two ports on the internal
header.
There is an on-board USB hub which provides:
- one external connector (bottom one)
- two internal ports on pin header
- one port for m.2 E connector
The top USB 2.0 connector comes directly from the SoC.
