1. A power tool comprising:
a housing including a motor housing portion and a handle portion;
a motor positioned within the motor housing portion, the motor including a motor axis;
a battery pack interface configured to receive a battery pack, the battery pack interface configured to be electrically connected to the motor for supplying electrical power to the motor; and
a printed circuit board positioned within the motor housing portion, the printed circuit board intersecting the motor axis, the printed circuit board including a conductive high impedance trace that is configured to interrupt electric power to the motor in response to a current that exceeds a current limit.
