Pixhawk - Lidar lite problem

Hi, When I try to connect Lidar lite via PWM it doesn’t work. I measured the power pins and I get only 0.03 volts when I should get 5 volts? Battery is connected, not USB

The Pixhawk does not provide power to the either the Servo Output Buss nor the Aux Output Bus.
You must power these two busses with a 5 vdc BEC for the LIDAR-Lite to work.
