Absolute maximum input voltage to the board is 35vDC. We rate it for 7-18vDC, however. Over 18 volts, you should keep an eye on temperature of the voltage regulator. It has thermal protection and will shut itself down, though.
Maximum input to the analog inputs (sensors) is 5vDC.
Volume control and temperature sensor must be connected with the red lead towards the chip.
We will document the other sensors connections - we were working so hard to get these shipped that we haven't taken pictures of proper connections yet.
You can expect pictures today.

Ya.....I was wondering when I was going to reach the bottom...
2-3 day USPS..
Oh... and one more thing...I would def say that it DOES matter which way the vol is connected. The first time I plugged it in, the red lead was towards the outside of the board and upon turning it all the way in one direction made the powere light dim and then window complained about an unknown device.
I unplugged everything and waited a sec, then plugged all back in and it continued to work, but this time I put the red lead towards the chip and well-la...no problems...You might want to inform and address this for future purchases...
Powering my at the moment w/ 15 volts...I don't think that changes anything with the vol b/c that is using the 5v, correct?
You're absolutely right, I was thinking of a different configuration for the volume that we'd discussed. I'm editing my post.
But, it really won't ever hurt anything, the voltage regulator will just go into overcurrent.

Glad to hear it works! And I am working on documentation for everything, expecially the software side. I didnt realize how fast these would get there. I figured at least until wednesday!
But if you take it out of the brown box, you get to the original box. So you can be afraid with 1 less layer of boxes if you wanted. Then if you unpack that white USPS box, you get a cool little white box. Then that is the final layer of fear, right inside there.
