Have you looked at the pcduino3 nano lite.<br>

$15 and it looks like it meets all your specs.<br>

<div>It has everything in the kernel and uboot and works
with Fedora 23 with no modifications.<br>
</div>
<div>I've got Yor Linux armv7 build working on it, so I'm
quite certain it will work with CentOS arm build, but I
have not tested it.<br>

Ah, I see it does have a sata port. I missed that the first time.<br>
<br>
And it looks like it has the 5V power out that will hopefully power
any HD up to 1A.<br>
<br>
If it uses the same uboot as the pcduino 3 nano, then I can take the
Cubietruck image and dd the appropriate uboot and boot.<br>
<br>
Have you tested it? The big test is to only have uboot on a 4Gb
mSD and the whole image on the Sata HD and see if it switches over
like the Cubieboard does. Otherwise there is a lot of customization
needed.<br>

features that have attracted me to ARMv7 are:<br>
<br>
1) Power consumption<br>
<br>
My ROI on power savings was 15 mo. with the Cubieboards over
my current Intel SFF boxes. And along with that is lower
UPS requirements and heating. I have 5 boards, plus drives
powered from one USB power supply.<br>
<br>
2) Board size<br>
<br>
With boards the same or smaller than a 25" drive, I truly
have an appliance that can be placed anywhere.<br>
<br>
Now there are few ARMv7 boards that meet my exacting
requirements: 1 or 2 MB ram (depending on appl), 2+ core,
and SATA interface.<br>
<br>
If all I have is USB, then I get the USB/SATA adapter cost
and powering thrown into the equation. Also a board that
has been moved into the mainline kernel and distro support.
RPi stands out as being a pain. 4-port LAN features require
kernel customization.<br>
<br>
I was talking with one manufacture that was meeting my main
req at $15/board. But they went for a mass-market target
and dropped the DIY one. I will be talking to them again
next month. But their board is not in the general sunxi
effort. Yet.

The big problems I have with the majority of the
development boards are:<br>
<br>
1) Memory<br>
On 32-bit ARM, the RAM was always limited to 4GB,
which would be find if there were a significant number
of devices available that ship with 4GB of RAM (minus
the various necessary memory holes). But that simply
isn't the case. I can think of hundreds of devices
with <= 1GB of RAM. I can think of only about 4
with 3-4GB of RAM (of which at least 2 are deprecated
and unavailable), including ARMv8 which is not limited
to 4GB. And two of those four are laptops.<br>
<br>
2) Memory Type<br>
We've been being told since forever that the main
reason why ARM devices don't come with DIMM sockets is
because they are 32-bit and DIMMs have 64 data lines.
Well, with ARMv8 we have those 64 data lines, and yet
there are precious few devices available featuring
DIMM sockets for memory. There are in fact probably
more dev boards in SODIMM form factor than there are
those featuring DIMM memory sockets.<br>
<br>
3) Board Form Factor<br>
There are painfully few ARM boards in *TX form factor.
Off the top of my head I can think of a total of 5, of
which one is positively ancient and probably no longer
available (Atmel, IIRC), one is deprecated, the
manufacturer of the 3rd appears to have gone bust, one
is on the underpowered side (VIA APC) and the 5th is
exorbitantly expensive (at €800 there is no incentive
at all to buy an ARM board instead of a much more
powerful, more fully featured and better supported
Xeon board).<br>
<br>
Worse, these variously deficient devices aren't
exactly cheap, either (well, apart from the Raspberry
Pis). I find the lack of supply of boards with
sensible features quite thoroughly baffling,
especially since the rock bottom features (if they cut
any more corners they'd be perfect spheres) don't
match the relatively high prices.<br>
<br>
Instead of leveraging decades of industry
standardization on the basics such as memory sockets,
form factor (including power supplies), almost every
ARM board manufacturer seems to be intent on
reinventing their own wheels, and doing a pretty poor
job of it, even though these problems have been
thoroughly solved for decades.<br>
<br>
Not that I think any manufacturers are listening...<br>

No sata for all that power.<br>
And draws a lot more power too.<br>

I will continue to wait to see what the Cubietruck
plus will be and how<br>
much. They put out the blog on it back in July.
And then Hans will<br>
have to get one to make the uboot for it...<br>
