GP2X Voltage Levels On The Ext Uart Lines

[MiniMoose]

Now that there are people selling connectors that fit the EXT port, does anybody know the voltage levels on the UART lines? The wiki page on the subject doesn't mention it.

I'm assuming that we need to use an RS232 line level converter to go from the 3.3V/5.0V levels of most devices to the 12V levels required for RS232.

Also, has anybody cut open ther TV-out cable yet to figure out which pins are connected to the video and audio out?

The lines are connected directly to the processor by the looks of it, so you'll need a level shifter as the voltage will be 3.3v

in my experience they were around 3.3v, yes

Thanks, Squidge. I also updated the wiki page on the EXT port to include the results of my connector research.
