Power Distribution Board (PDB)

The custom PDB is engineered to handle high-current throughput required for quadrotor drone.

• Construction: 2 oz copper trace on a 2-Layer Power PCB.
• Thermal Design: Stitched layers to allow for the high amperage draw of the motors.
• Protection: Individual fuses for each ESC via XT30 connectors.
• Connectivity: Integrated XT60 battery lead and dedicated header pins for the Buck Converter and MCB.
• Grounding: 2x4 Header Pin Block ensuring all ESCs and the MCB share a common reference ground.

Aerodynamics

Theoretical parameters and lift calculations are derived using the following thrust model:

$$\text{Thrust per motor} = C_\tau \rho \omega^2 D^4$$

Where:

• $C_\tau$: Thrust Coefficient (dimensionless)
• $\rho$: Air density [kg/m³]
• $\omega$: Propeller angular velocity [revs/s]
• $D$: Propeller diameter [m]

Note

Please refer to DroneSetup.py for specific aerodynamic calculations and theoretical drone parameters. (This will be further expanded on later).
