The FlightCtrl is already fitted with all needed components.

{i} The FCV2.1 can be connected to the powerboard via the molex cable.

When using the Molexkabel between FlightCtrl and powerboard, you don't have to solder the I2C bus, the buzzer and the power cable to the FlightCtrl.
Only the power cable for the receiver still has to be soldered to the FlightCtrl.
The buzzer is connected directly to the appropriate solder points of the powerboard (Buzzer / -).
The I2C-bus and the voltage supply are provided from the power distribution via the Molex.
Alternatively, the FC V2.1 can be connected with individual cable to the power distributor. But then you don't have to use the Molexcable.

/!\ When mounting the FlightCtrl, the printed arrow shows to the rigger No.1 (red rigger). The PCB populated side facing up.
