RE: [Gumstix-users] Newbie GPIO question

[Brian G. <br...@in...>]

The motor controller specs say 2.5-5.5V logic so I think I'll be fine.
Thanks a lot for the help. I'll let you know how it goes.

Hi Brian,

That might work. The GPIO lines on the breakout board are 3.3v logic
levels, so if your motor controller is compatable with that, then it
should work fine.

If not, you'll need some voltage conversion.
