<div>Hi,<br>
</div>
Have you looked at the pcduino3 nano lite.<br>
</div>
$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>
</div>
<div><br>
</div>
<div>There are two downsides to this board.<br>
</div>
<div>1 - the sata (and power cable) are sold
separately<br>
</div>
</div>
</div>
</div>

<br>
</span> 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>
<br>
</div>
</blockquote>
<div><br>
</div>
<div>Yes, I've tested it. It used the same uboot and kernel
dtd as the pcduino 3 nano.<br>
</div>
<div>I have a couple of the pcduino 3 nano machines and
ordered a couple of the lite's, so I've used both. I used
the nano uboot on the lite and it worked with no
modifications. I also did nothing with the kernel and it
worked great.<br>
</div>
</div>
</div>
</div>
</blockquote>
<br>
I just ordered one. I will see how it goes and make an acrylic
standoff arrangement for it and a drive. I wnet cheap on delivery
so I won't see it until the 4th.<br>
<br>
I am going to see if with Centos, I can control the adunino
connectors and have some sensors working off the board.<br>
<br>
But I really want to find an affordable 4 core as I have mentioned
before.<br>

Nice that they put it off to the side. But that would

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>
