➢ Servo power
FC 5V BEC(PMU): Use solder to connect the two pins shown in the picture, and disconnect
other BEC of the servo (such as the built-in BEC of the ESC).
External BEC: If you do not connect the two pins shown in the figure, the external BEC is
used by default. The BEC can be connected to any channel among S1-S8.
It’s recommended to use the supplied 3300uF/16V capacitor to get a more stable and
secure working voltage for the PMU. The capacitor can be plugged onto any one of the
free input or output sockets of the FC.
