Concept & Designs

The Raspberry Pi Zero 2W serves as the core processing unit for the drone. It is responsible for running the flight control algorithms, which manage the overall flight dynamics and stability. The Raspberry Pi communicates with the SpeedyBee F405 V3 Flight Controller to send control commands and receive feedback, ensuring that the drone operates smoothly. It also handles wireless communication via Bluetooth, allowing for easy setup and control during operation. The Raspberry Pi's flexible computing power enables the integration of additional features like real-time telemetry, sensor data processing, and user-customized flight behaviors. 

The SpeedyBee F405 V3 Flight Controller is the brain that manages the drone's flight stability and motor control. It receives instructions from the Raspberry Pi and translates them into motor control signals for the Readytosky RS2205 2300KV Brushless Motors. This flight controller is designed to provide smooth and precise control over the drone's movements, including pitch, roll, yaw, and throttle, based on the flight algorithms running on the Raspberry Pi. The SpeedyBee F405 V3 is known for its robust performance and low-latency response, ensuring that the drone can react quickly and accurately to input commands. 

The Readytosky RS2205 2300KV Brushless Motors are crucial components for the drone’s propulsion. These motors are capable of spinning at high speeds, providing the thrust needed for stable flight and responsive control. The 3-4S rating means the motors can operate efficiently with a variety of battery voltages, making them versatile for different flight setups. With their CW/CCW rotation, they work in pairs to provide balanced thrust, allowing the drone to perform stable maneuvers in all directions. These motors are specifically selected for their power and durability, making them ideal for FPV racing drones and other high-performance applications. 

Bluetooth communication is used to link the Raspberry Pi Zero 2W with the SpeedyBee F405 V3 Flight Controller and other components. This wireless communication allows for easy configuration and control of the drone without the need for wired connections or bulky radio controllers. It simplifies the setup process, enabling real-time interaction between the user and the drone. Bluetooth also supports data transfer between the Raspberry Pi and external devices, such as ground stations or other drones, making it an essential feature for remote control and system monitoring during flight. 

The Geekworm X306 V1.3 UPS Expansion Board provides stable and reliable power management for the Raspberry Pi Zero 2W. It ensures that the Raspberry Pi receives consistent power during flight, preventing abrupt shutdowns in case of sudden power loss. This board also allows for safe shutdowns, protecting the Raspberry Pi from potential damage due to power interruptions. By maintaining a stable power supply, it ensures that the flight control system remains operational throughout the flight, allowing for reliable performance and control. 

The OVONIC 6S Lipo Battery 100C 1300mAh provides the necessary power for the drone’s motors and flight systems. With a high 100C discharge rate, this battery can deliver the required power during high-demand situations, such as rapid maneuvers or high-speed flights. The XT60 connector ensures a secure and efficient connection to the drone's power system. This battery offers a balance of high capacity for extended flight times and the necessary power output for performance, making it a key component in maintaining the drone’s efficiency and longevity. 

The HC-SR501 Infrared PIR Motion Sensors are used for basic obstacle detection in the drone. These sensors detect movement in the drone’s path and can trigger safety protocols to avoid collisions. For example, if the sensor detects an obstacle, the drone can automatically adjust its flight path or initiate an emergency stop to prevent crashes. These sensors add a layer of safety to the drone, ensuring that it operates autonomously without colliding with objects in its vicinity.
