Power Distribution Panel
Next, we'll take a look at another component from CrossTheRoad.

Of course, this name is stamped on the new power distribution panel.


Power Distribution The Power Distribution Panel


The new power distribution panel has 8 positions for 40 amp snap-action breakers, and 8 positions for 20/30 amp snap-action breakers. These positions came labeled as specific channels, which makes us wonder what other capabilities we might see out of this CAN enabled board.

On the bottom right we have CAN connectivity. The PDP board has a configurable jumper next to the CAN Input/Output that can define it as a a terminator for a CAN chain. In other words, the PDP can be at the start or end of your CAN network.

Along the bottom of the PDP you can see the power lugs on the left. There was a bit of a headache here, because our lugs were within about 1/16" from the CAN circuit board. We spaced the lug out by putting a washer under it. If the board had its case this wouldn't be an issue.


Power Connectors Power Connector Close-Up


Along the top of the PDP are fuses and power connectors. The red and black connectors next to yellow 20 amp fuse are for the Voltage Regulating Module and the Pneumatic Control Module. The blue on the top left are for the roboRIO.

This panel is slightly smaller than the old one, and measures in at 7.5" x 5" x 1.25". To be fair, this is with no plastic shell.

Finally, comes the weight. The new power distribution panel weighs in at 462 grams. It seems like quite a bit after holding the pneumatic control module and voltage regulator modules, but in reality it is still a bit lighter than the old PD board. We'll see if that remains true once they put a plastic skin on it.
