Compared to other boards, the main selling point here is extremely compact size and ability to be plugged into a breadboard. USB OTG, functional wifi+bt, and a footprint for SPI flash round out the distinguishing features.

The Duo2 is a small narrow black PCB, densely packed, with "NanoPi Duo2" in very small silkscreen.
The PCB has the following silkscreened on it:
NanoPi Duo2 v1.0 1807
Supported in mainline from 5.5
FriendlyARM provides both 4.14 and 3.4 legacy trees.
- https://github.com/friendlyarm/linux.git -b sunxi-4.14.y
There's very little reason to use this tree. The board is supported by 4.14 from FriendlyARM themselves, and in mainline from 5.5. The tree is available at https://github.com/friendlyarm/h3_lichee.git with [| documentation on the FriendlyARM wiki]
You can build things for yourself by following our Manual build howto and by choosing from the configurations available below.
There's no explicit duo2 support in U-Boot, and it's unclear if that's valuable. The FriendlyARM_NanoPi_Air is equivalent for most purposes. Providing a separate name for the duo2 would be a trivial patch if desired.
Use the sun8i-h3-nanopi-duo2.dtb device-tree binary.
Not documented as not considered useful at this stage.
No FEL button, the UBOOT pin is pulled up via 10K.
A red and green led are available. The red is pulled up, and intended as a power indicator. Green is free for use.
The Ampak AP6212 is quite well supported by linux, but it does require suitable firmware files, both for the wifi portion, and the bluetooth portion.
Locating the UART
The primary debug uart (uart0) is on the GPIO2 header, at the end nearest the USB connector. There is silk marking RX/TX/Ground.
