NSSL EFM Motor Control PCB

One of the paddles on the instrument houses a motor driver, which reads motor speed
from an encoder and controls power to the motor to maintain a constant rotation rate
of the instrument. We also monitor the current supplied to the motor and the
temperature of the control board, logging all of this data to a rolling log file.
This log is used for debugging and diagnosing any flight-related failures.

See the main instrument repo for documentation and the rest of the instrument.
