Ethan,
The digital side car jumpers are there to supply 6 volts for servos. If you remove the jumpers there is no voltage. There is no easy way, using the digital side car, to provide 4.8 volts to the servos you linked to in your post. If the GDC allows this variation then we can discuss some alternatives.

So basically if they don't allow the voltage regulator, I'm going to have to find another servo :/

Re: Voltage regulators

Wouldn't the power converter included in this years KOP work?

360 CPR

12V to 5V, Step-down, 5A, 25W

Yes it would, but rule <r48> says it must be regulated by an approve power regulator controlled by the cRIO

Quote:

<R48> All electrical loads (motors, actuators, compressors) must be supplied by an approved power
regulating device (speed controller, relay module, or Digital Sidecar PWM port) that is
controlled by the cRIO-FRC on the ROBOT.

A. Each CIM motor and Fisher-Price motor must be connected to one and only one
approved speed controller. These motors must not be connected to relay modules.

B. Servos must be directly connected to the PWM ports on the Digital Sidecar. They must
not be connected to speed controllers or relay modules.

C. If used, the compressor must be connected to one and only one approved relay module.

D. Each other electrical load (motor or actuator) must be supplied by one and only one
approved speed controller, or one and only one relay module.

$60 for a servo? Wow. Sparkfun and Parallax sell servo's that are compatible with 6V for $13, and I'm sure there are many other sources too.

Yes, but look at the servo's torque. You can't stop it with your hand.

Re: Voltage regulators

Comparable servo @ 6V...

Thanks, but that goes over the 4Watt limit and its digital instead of analog.
