Propeller Controller Board Running Parallax GPS OK Without Resistor?

[hover1]

All right, before you tell me to go the the website, and download the PDF,·I already have and have talked to Josh in tech support. http://forums.parallax.com/images/smilies/tongue.gif


I purchased a few of the now discontinued Pararallx Control Boards (#28205). I recieved·some REV A and some REV B boards. Does anyone know what the difference between the two are?

Also, does anyone know if there is a resistor between the GPS SIO pin and the Propeller P21? My old eyes are trying to trace out right now.·I figured Parallax would put one between a 5V and 3.3V device.

What will the Stingray control board look like? Can't wait.

Just a question to see if Parallax has given the OK to run the the Parallax GPS (#28146) on the Quad Rover Propeller Controller Board (#28205) without a resistor in line, (as the board is laid out)?

If anyone has a Rev B. PDF I would be most thankfull.

And the 330uh coil that is on the board does not show up in the schematic.

Any help on documentation would be appreciated.

Thanks Rich,

I guess I should have said what will the schematic look like. http://forums.parallax.com/images/smilies/smile.gif

I followed UPEW from afar and caught some of the sting ray photos and write ups·by Chris. Just thought I would get a couple of these boards to do a super BeoBot, but documentation seems a little lacking. A full Parts·Placement would help. I am trying to figure out what the 6082a chip is just below the GPS and to the right of the power switch.

I realize it·was a short run board to be used on the Quad Rover only, but I think Quad Rover owners would also·need this information.
