What purpose does this board serve?

The purpose of the backplane is to Routes signals to everything on the vehicle

To what boards (or enclosures etc) does it connect?

The backplane connects to the pi shield, power distribution, ESC controller, and ESC boards

What priorities did you have in your design? What design considerations did you have? What methodologies did you follow? (routing a differential pair, keeping something separate for isolation, etc)

What changes were made to your board from the previous year(s)?

What factors affected your board outline?

What reference materials did you use for circuits? (Provide links to these)

What is the throughput of your board (power, data/speeds, etc)?

Output: 3x 12V (50A), 5V GND to pi shield, 3.3 V (1A) to ESCs Input: 12V (100A) GND, 5V (3A), 3.3V (1A) from Power Distribution

Why did you pick certain components for your board? (If you don't know the answer/were told, now is a great time to ask)

What issues did you have with your board (in both design and assembly)

How did you go about integrating with mechanical? What changes did you make?

Other notes: what else about your board should be mentioned?

What errors/mistakes were made?

If you had to do it over again, what might you change?

What did you do that was spot on?

Tech Report Paragraph

The Backplane routes signals throughout the ROV, it receives 12 V, 5 V, 3.3 V from the Distribution Board. It then sends those power rails along with other signals such as the data lines from the Bricks Boards and the CAN bus to the ESC Adapters, the ESC controllers, and the Pi Shield. To ensure enough current for the ESCs, 12 AWG wire was soldered directly to the board for the 12-V line. Due a lack of space in the power box, the solenoid board and its respective signals were condensed to the Pi-Shield.
