PD board - great; no complaints.
cRIO - power connector is TERRIBLE. Are there any other options here?
Breakouts/Bumpers - great; no complaints.
Sensors - great; no complaints. Love that the gyro and accelerometer come on the same board, but can be easily separated.
Digital sidecar - we had a couple of issues where the 5V rail on the DSC got shorted by debris near the connectors. If the plastic housing were a bit larger, this probably wouldn't have happened.
Radio - clearly not designed for use on a robot
We had to carefully mount it to stop the reset button from pressing itself.
OVERALL:
My biggest complaints are things that can't be easily changed as far as I can tell. Boot time is way, way too long. The cRIO is big and heavy.
