I was looking here: http://docwiki.gumstix.org/index.php/Console-vx previously I learned that the voltage levels of the UART off the verdex board are 3.3v and need to be 5v to talk to the robostix. Does the console-vx change these voltage levels to 5v? Can I just interface with the console-vx to talk to the robostix over the UART? Thanks.
