And here is the H3 datasheet.
It requires a 4mm x 1.7mm DC barrel jack (same as used on Sony PSP). Center positive.
I dig through my junk box and find two Toshiba branded power supplies labelled 5 volts, 2 amps with the correct barrel connector. I am hoping since they are a name brand they will actually be able to deliver a solid 2 amps and that problems reported by others are due to dodgy no-name supplies. After several months using these with absolutely no problems, I am satisfied that these are fine.
There are no messages whatsoever on the serial console from the boot loader. It is easy to see why some people receive these boards and think they are dead.
I am using a brand new 8G SanDisk microSDHD UHS-1 card that claims "speeds up to 48Mb/s".

A bunch of stuff starts streaming across the screen and before long I have a prompt to login! I login as root with password "orangepi".

Odd that linux does not report processor speed. Just plugging in a network cable does not get the network going, nor does "service network restart". There is talk that I need to copy in a proper
I have vi, perl, and python. No ruby. No C compiler.
These instructions work correctly for the Fedora 22 image as well. Even if it seems like your operating system is working correctly, you will need to create the correct script.bin and uImage file as directed. In particular, the Fedora 22 image is bad. The Ethernet port doesn't work. Also, you should remove uImage-* and script.bin.* for simplicity.
This is all you need:

script.bin.OPI-PC_720p60 uImage_OPI-2These will go into the boot partition on the SD card, but renamed to leave off the OPI suffixes.
This is all somewhat mysterious, but note that the boot partition in the running system is mounted as /media/boot and looks like this:
