Chumby 3.3v TTL servo controller

Hi,

Will the “Micro Serial Servo Controller” work with TTL of 3.3v ?..
I have a Chumby and we are looking to use the Micro Serial 8 Servo Controller for some Bot building, the TTL level on this device is 3.3v not 5v…

Reference.

Thanks

Hello,

The 3.3 V level will not be reliable for use with the servo controller’s logic-level input, which can have a threshold as high as 4 V. If you can invert the signal, you can feed it into the RS-232-level input, which has a lower threshold.
