What is the drone servo connected to?
The UAV steering gear is a key component in the UAV flight control system and is responsible for controlling the attitude and direction of the aircraft. Understanding how the servos are connected is crucial to the assembly, commissioning and maintenance of the drone. This article will introduce in detail the connection method of the drone servo, and combine it with the hot topics and hot content on the Internet in the past 10 days to provide you with a comprehensive reference.
1. Basic connection method of drone servo

UAV servos are usually connected to other components in the following ways:
| Connecting parts | Connection method | Function description |
|---|---|---|
| flight control board | PWM signal line | Receive control signals from the flight control board and adjust the steering gear angle |
| power supply | Power cord (positive and negative) | Provide operating voltage for the steering gear |
| Mechanical structure | connecting rod or gear | Convert the rotational motion of the servo into mechanical action |
2. Popular drone topics in the past 10 days
The following are the recent hot topics and hot content on drone technology across the Internet:
| topic | heat index | Main content |
|---|---|---|
| Intelligent upgrade of drone steering gear | 85 | Discuss how to optimize steering gear response speed through AI technology |
| New lightweight steering gear material | 78 | Introducing the application of carbon fiber composite materials in steering gear manufacturing |
| Drone steering gear waterproof technology | 72 | Discuss how to ensure the normal operation of the steering gear in adverse weather conditions |
| Open source flight control and servo compatibility | 68 | Analyze the matching issues between different open source flight control systems and various types of servos |
3. Specific steps for connecting the servo
1.Connect the flight control board: Connect the PWM signal line of the servo to the corresponding output port of the flight control board. Pay attention to the positive and negative directions of the signal line.
2.Connect power: Make sure the operating voltage of the servo matches the power supply. Usually an additional BEC (battery elimination circuit) is required to power the servo.
3.Mechanical installation: According to the design requirements of the UAV, connect the steering gear to the corresponding control surface (such as ailerons, elevators, etc.) through connecting rods or gears.
4. Common problems and solutions
| question | Possible reasons | solution |
|---|---|---|
| The servo does not respond | Incorrect power connection or poor signal line contact | Check the power and signal cable connections to ensure good contact |
| Servo vibration | The power supply voltage is unstable or signal interference | Add capacitor filtering or use a regulated power supply |
| Servo overheated | The load is too large or the working voltage is too high | Check whether the mechanical structure is stuck and adjust the working voltage |
5. Future development trends
With the continuous development of drone technology, the connection methods of servos are also constantly innovating. In the future, there may be a wireless servo control system that communicates directly with the flight controller through Bluetooth or Wi-Fi, reducing the complexity of cables. At the same time, smart servos may integrate more sensors to achieve more precise control.
In summary, the connection of the drone servo involves both electrical and mechanical aspects, and the correct connection method is crucial to the flight performance of the drone. By understanding the latest technical trends and hot topics, we can better master the connection skills of the steering gear and improve the overall performance of the drone.
