The backbone of the system, the Raspberry Pi 5 manages optical and thermal imaging, and seamlessly coordinates data across all three main boardsIn progress

The Sixfab modem interfaces directly with the Raspberry Pi 5, enabling 4G LTE connectivity. It mounts as a HAT, matching the Pi’s footprint for a compact, stackable design

The Pixhawk 2.4.8 is a low-cost, reliable flight computer capable of running ArduPilot or PX4. It controls the drone’s flight surfaces and manages GPS-based navigation

 The Seek Thermal Pro is an ultra-compact smartphone thermal camera supported by a large maker community. An open-source API allows seamless integration with Linux systems.

 The 1080p USB camera from Arducam—widely trusted in Raspberry Pi projects—offers greater flexibility for gimbal movement compared to CSI-based modules.

 All custom parts were 3D printed using the Bambu Lab X1 Carbon, with designs modeled in Fusion 360 for precision and fast turn around times.

 12A ESCs (Electronic Speed Controllers) regulate motor speed by converting throttle signals from the Pixhawk into precise power delivery, using high-frequency PWM. They draw power from the main distribution board and interface directly with the flight controller.

 Brushless ReadyToSky motors were selected for their strong performance and affordability. Throughout testing, multiple motors were sacrificed in the pursuit of reliability and refinement.

 Jumper cables with Dupont connectors are used throughout the drone, allowing for quick configuration changes and easy routing through the frame.
