This diagram shows the wiring setup for a quadcopter drone using a PX4 flight controller.Motors (1–4): Four brushless motors connected to the ESCs (Electronic Speed Controllers), which control motor speed.Propellers: Attached to the motors via prop adaptors.ESCs: Linked to the PX4 FMU board through servo cables for signal control.Battery: A LiPo battery powers the entire system via a battery connector and balance charging lead.External BEC: Provides stable power to the flight controller and other components.GPS Receiver: Connected to the PX4 for positioning and navigation.FrSky Receiver: Handles communication between the remote control and the PX4 flight controller.Multi-Port Connector: Central hub for power distribution and signal wiring to the PX4.In short, this is the complete wiring layout to power, control, and navigate a quadcopter.
