Boebot CMUcam

Humanoido

I have the Boebot CMUcam and need to know
which pin ports on the BOE BS2 are open and available.

The CMUcam board plugs into the appmod header
and the pins are labeled on the BOE. But which
ones are used and unused?

I checked the manual at the Parallax download
site and the manual at the CMU site, and the
"pins used" diagram for the Boebot is not listed.

I also have several schematics which do not
match the BOE. Any help would be appreciated.

The BOE uses I/O pins 12-15 for the servo connectors. If you are not using one of the servo connectors, that I/O pin is completely available.
The schematic for the BOE has a link on the BOE webstore page.

Thanks Mr. Green. The idea of the servo pins helped
solve the problem. The pins on Boe were traced to
the APPmod connector, then to the CMUcam where
pins were found open and n/c. A camera in microscope
mode was used to image the remaining pins and then
a rough CMUcam pinout was drawn, relative to BOE.
This was compared to traces on both board sides to
determine the remaining unused pins. The unused
pins can now be used for Boebot sensor expansion
when the CMUcam is in place.
