This is a low-cost Allwinner A20 board with Arduino-style GPIO headers; it features 1G RAM, 4G NAND flash, 1 micro-SD, 2 USB sockets, 1 micro USB socket for OTG and another for power in, HDMI, SATA, 5V power for SATA devices, gigabit Ethernet, an IR receiver, 3.5mm audio out and a MIPI camera connector.
Like the BananaPi, this board needs GMAC_TX_DELAY set to 3 in order for GMAC to work reliably at gigabit speeds.
For more details, see: http://linux-sunxi.org/LinkSprite_pcDuino3_Nano
Changed in v3: - add CONFIG_GMAC_TX_DELAY=3, which corresponds to a patch in LinkSprite's A20 kernel; testing shows the performance is now much better at 1000M
