Re: Team 4719 Bulldog's (Main) Electrical Board

Nice work, Matt! The layout of the components looks well thought out.

Consider where your battery will be mounted when looking for a place to mount your breaker (keeping it accessible from outside your robot).

It may be best to separate the CAN wires connecting the Talon to the PCM from the power wires running to the VRM and PCM. When your compressor draws current, it can induce noise in the CAN wires that are running in parallel and nearby. Movinr the power wires to where the power wires for the RoboRio are should give enough separation to dramatically reduce the noise coupling.

I am guessing that you put the Anderson connectors on the power input wires of your Talons to make replacement easy and so they can easily be reused in subsequent years. It is not clear how you connected the CAN wires between the Talons. You may want to consider using the locking connectors from Hansen Hobbies. We just got ours in and they work quite well. They use different pins from the PWM connectors that Hansen sells but the same crimper will work for both. So far, it is probably the connector that will introduce the least disturbance, impedance wise, on the CAN Bus and is still easily accessible to FRC teams.

It looks like the power wires to your DLink are run around the back of the board. You may want to add some tape to keep the connector securely plugged into the DLink.
