Once we got our test bot up and driving with the new control system, we noticed something odd.
One of our Jaguars (and only 1) makes a very interesting high pitched squeal. This occurs with the fan on or off, with the system enabled or disabled. We've checked the wiring, removed the PWM, and it continues. The pitch changes slightly when the LED blinks.
Did our Jaguar swallow a chipmunk, or is something else going on?
