Re: Electrical Diagram for the Power Distribution Board
What do you mean by broke?
Also, beware of R65:
Quote:
4.1.9.11 R65
The Driver Station software, cRIO, motor controllers, relay modules, wireless bridge, and batteries shall not be
tampered with, modified, or adjusted in any way (tampering includes drilling, cutting, machining, gluing, rewiring,
disassembling, etc.), with the following exceptions:
Please note that the Driver Station application is a separate application from the
Dashboard. The Driver Station software may not be modified, while teams are expected
to customize their Dashboard code.
A. User programmable code in the cRIO may be customized.
B. Dip switches on the cRIO may be set (applies to cRIO-FRC only).
C. Motor controllers may be calibrated as described in owner's manuals.
D. Fans may be attached to motor controllers and may be powered from the power input terminals.
E. If powering the compressor, the fuse on a Spike H-Bridge Relay may be replaced with a 20A Snap-Action
circuit breaker.
F. Wires, cables, and signal lines may be connected via the standard connection points provided on the devices.
G. Fasteners may be used to attach the device to the OPERATOR CONSOLE or ROBOT.
H. Labeling may be applied to indicate device purpose, connectivity, functional performance, etc.
I. Brake/Coast jumpers on motor controllers may be changed from their default location.
J. Limit switch jumpers may be removed from a Jaguar motor controller and a custom limit switch circuit may be
substituted.
K. If CAN-bus functionality is used, the Jaguar firmware must be updated as required by FIRST (see Rule R68-D).
L. The First Touch I/O module’s firmware may be modified.
Note that if you are using the FirstTouch I/O module as part of the OPERATOR
CONSOLE, you should not update the firmware if the manufacturer releases a new
version. The new version will wipe out the FIRST custom firmware and your FirstTouch
I/O module will no longer function with the Driver Station software. If a team does wipe
out the FIRST custom firmware, it can be restored via the most recent Driver Station
update.
M. Devices may be repaired, provided the performance and specifications of the component after the repair are
identical to those before the repair.
Please note that while repairs are permitted per the FRC Game Manual, the allowance is
independent of any manufacturer’s warranty. Teams make repairs at their own risk and
should assume that any warranty or RMA options are forfeited. Be aware that diagnosing
and repairing COMPONENTS such as these can be difficult.

While repairs aren't illegal, you are advised that they may be difficult.
