Howdy dumbak,

You're correct, you get 1.8V logic out those lines. If you want to connect
to anything you'll need to run them through a level converter.

Subject: [Gumstix-users] Tobi board logic levels

Hello,

I would like to ask which logic levels uses Tobi Board on GPIO148_TXD1 and
GPIO151_RXD1?
I found its 1,8 GPIO, is it coresponding with these (1,8V CMOS)?

Thanks for advices
dumbak

One of the wikis suggests a level shifter, that I have used with success.
