Interesting use of energy chain, I like it. I'd be worried about that tight bend on the wire between the PDP and breaker- looks like it's being pinched quite a bit.

I understand your pain of having a limited space... we're probably going to have a main electronics board about that size - if we're lucky

How the board will exactly mount to the chassis is being debated. To get the tight radius on the wires, we bent them before crimping the connectors. This way, the stands were aloud to shift around the radius (the inside wires of the bend were longer then the outside, naturally). The CAN wire is longer then what it looks like, it is beneath the radio. All of the wires that leave the board are 2 feet long.

We had a discussion about pull testing the ends, and I can assure you that all of them were yanked on multiple times.

The battery connection has changed since the picture, it now bends around under the board were it will be mounted to a plastic block else on the robot.
That would be cool to see. The pull test got our electrical failure rate way down in the last two years.

I am currently working with my son to lay out our electronics inside our robot. With the mechanical design we have, it will be even more tight than what you have.

Looks very neat! The only thing I can comment on is the radio. This is a new radio so teams don't have a lot of info or in match data. However, the antennas for this radio exist just behind the sides of the radio so placing the radio near any metal will tend to attenuate the signals and provide serious reflections to the RF transmit circuitry. My recommendation is to place the radio high in your robot away from metallic structures for best performance.

Mentor Mac here. More then likely it will fail inspection. You won't be able to see the lights on the radio by the FTA's and the Refs. 2nd You will bury the main breaker from easy access. That's a no, no, sorry. Thomas (just give me a crabcake) McCubbin God Bless
