Note that the wiring in this robot has been torn down, so I am unable to take any more pictures or scope shots until we get it rebuilt.

I can probably take some more scope shots when we get it rebuilt using the breakout boards in a day or two. I expect that we will so little to no noise on 3.3V rail since it will only have a short ribbon cable connected to it.

We are changing over to shielded wiring to go from the breakout board out to the encoders, so that should greatly help the 5V line to not pick up any noise, and of course the encoder cables will be run separately from the motor wires now.

I would like to re-emphasize that our original implementation was flawed, it is not good design practice to run signal wires in close proximity to high current motor wires for any significant distance. I also think that the idea of using this super tiny ribbon cable to go all the way out to the encoders was flawed, since this ribbon is just not very robust.

It is much better and more reliable to run the ribbon a short distance out of the talons and then use the breakout board to switch over to a more robust shielded cable to go the long distance to the encoder.

Hindsight is 20/20, but for any other teams out there that see this thread please think about this when designing and building your robot.
