Drones & Accessories

Acts as the "brain" of the drone. It integrates IMU (gyroscope + accelerometer), barometer, and main control chip. It reads sensor data hundreds of times per second, calculates attitude deviation through PID algorithms, and outputs PWM/DShot signals to ESCs to correct motor speed.

Receives satellite signals and calculates latitude, longitude, altitude, and speed through triangulation positioning. Uses a compass (magnetometer) to determine heading direction.

Receives radio signals from the ground transmitter (e.g., SBUS, CRSF protocols), decodes them, and converts them into control channel data recognizable by the flight controller.

Converts the battery's high voltage (e.g., 22.2V) through buck circuits to stable low voltages (5V/3.3V) required by the FC and peripherals, while monitoring current and voltage data in real time.

Based on electromagnetic induction, it uses three-phase AC current to generate a rotating magnetic field in stator coils, driving the rotor permanent magnets to rotate and converting electrical energy into mechanical energy.

Acts as the "translator". It receives weak signals from the FC, controls internal MOSFET switching, and inverts the battery DC into three-phase AC to precisely regulate motor speed and direction.

Utilizes aerodynamic airfoil design. When rotating, the upper and lower surfaces create a pressure difference (Bernoulli principle), generating upward lift or forward thrust.

Lithium polymer batteries convert chemical energy to electrical energy through lithium-ion intercalation and deintercalation between electrodes, capable of instantaneous high-rate current discharge.

Modulates the video signal captured by the camera onto a specific radio frequency (e.g., 5.8GHz analog or 2.4GHz digital encoded signal) and transmits it through a power amplifier.

As an impedance matching converter, it transforms high-frequency current from the transmitter into electromagnetic wave radiation in space, or captures electromagnetic waves and converts them to current.

Tunes to the same frequency as the transmitter, demodulates the received radio waves, and restores the video signal for display on a screen or goggles.

Focuses light through lenses onto photosensitive elements (CMOS/CCD), converting optical signals to electrical signals and digitizing them; or emits laser/infrared to detect environmental data.

Uses brushless motors and IMU data through inverse compensation algorithms to maintain absolute camera axis stability during violent attitude changes of the aircraft (three-axis stabilization).

Made of high-strength lightweight materials such as carbon fiber, designed with structural mechanics to fix motors, ESCs, FC, and other components in specific geometric positions, forming a rigid assembly.

Landing gear provides ground clearance to protect bottom-mounted equipment; screws and adhesives connect components through friction and chemical bonding.
