It is the one shown in the photos. As far as soldering is concerned there are only two potentially tricky connections to the pins of the CM108 but as I pointed out if you use the right size wire and tack it on it is not a big deal. You might be surprised how easy it is. At $3 each sacrifice one to experiment and maybe it won't even be a sacrifice! The rest of the components you can mount or build anyway you desire. It is shown in a DB25 shell but that is certainly not a requirement. At first I was going to put a little perf board in there but then realized that most of the components could be mounted right of the connector. <br id="FontBreak"></font><br><b><font style="font-size:16pt;" size="4">73 Doug</font><font style="font-size:16pt;" size="4"><br></font><font style="font-size:16pt;" size="4">WA3DSP</font><font style="font-size:16pt;" size="4"><br></font><font style="font-size:16pt;" size="4">http://www.crompton.com/hamradio</font></b><font style="font-size:16pt;" size="4"><br></font><br><br><div><hr id="stopSpelling">Date: Wed, 24 Jun 2015 11:44:16 -0600<br>From: mike@mtweb.net<br>To: arm-allstar@hamvoip.org<br>Subject: Re: [arm-allstar] A simplified USB FOB modification<br><br>

<div dir="ltr"><font style="" color="#000000" face="Tahoma,sans-serif">I often get requests for GPIO
control of COS and PTT on the BBB and RPi2. While we are
going to have that capability in the next release at least
for the RPi2 I often wonder why the great desire to do
this and what the problem is with just modifying the FOB.
No matter where the I/O control comes from you still have
to build a minimal interface for the signals. Having it
all come from one place, the FOB, has several advantages.
One is you can use the code as it is now, the other is is
you are not tying up I/O on the main board and running
wires from two different places.<br>
<br>
In our testing I have built and tested it both ways GPIO
from the RPi2 or the FOB and I honestly think it is easier
to just modify the FOB. I have written an article showing
an easy way to modify the FOB that I think most hams who
have soldering and small construction experience could
handle. It saves you about $70/node to do this and a
couple of hours of your time. The article is in the how-to
section at <a href="http://hamvoip.org" target="_blank">hamvoip.org</a> <br>

For me, it is my eye site, isn't as good as it use to be and
everything has gotten way to small.<br>
Just finished up building a controller and had to use a 5x
magnifier. At least when you bread board stuff you can space things
2 microns further apart than half an atom:)<br>
I think most hams are older now. I don't see the younger crowd
getting in to the hobby, sad to say. So size of stuff is more
important to me now. As I wont tackle a project that requires a lot
of smt components.<br>
