Servo moves "randomly" on initialization of script? Moderators: adafruit_support_bill, adafruit

The Power pins are not controlled by the PCA9685. The OE pin controls only the signal output.

Yep. Sorry for the confusion. The fab print may illustrate it even better:

As you can see, the 5V power rail is a simple trace which runs the whole length of the pins and is always connected.

The Power pins are not controlled by the PCA9685. The OE pin controls only the signal output.

So in that case it seems unlikely that the OE pin would solve the issue I'm having? Any ideas? Or is this just a thing that happens on initialization that nothing can be done about?

Hard to say since it is not entirely clear what the source of the problem is. If it is spurious noise, than OE is not going to help. If it is some arbitrary signal going out before you have everything initialized, then you could use OE to suppress the signal output until you knew everything was fully initialized.
