When it comes to drones and remote-controlled vehicles, there are all kinds of acronyms and technical terms that can be overwhelming to the average person. One of these terms that often confuses people is “S.Bus” and “iBus”. So, what exactly is the difference between these two?
In short, S.Bus and iBus are both protocols used for communicating between your transmitter (e.g. your controller) and your receiver (e.g. the thing that makes your drone move). However, they have some key differences in how they work and what kinds of hardware they are compatible with. Understanding these differences can help you choose the right equipment for your specific needs.
If you’re new to the world of drone flying or remote-controlled cars, it can be hard to know where to start. There are so many different types of controllers, receivers, and other equipment out there that it can be overwhelming. That’s why it’s important to understand the basics, like the difference between S.Bus and iBus. With a little bit of knowledge, you can make an informed decision and get the equipment you need to have fun and fly safely!
Understanding Sbus and Ibus
One of the biggest challenges of remote control technology is the limitation of the number of channels you can use to connect to a receiver. Previously, radio controlled toys could only send and receive signals through one or two channels, limiting the level of control you could exert over them. Nowadays, with the advent of digital signal processing, we can use protocols such as Sbus and Ibus to send more channels over a single wire.
Benefits of Sbus and Ibus
- Higher resolution: With more channels available, Sbus and Ibus can provide higher resolution control of your receiver, allowing you to make more nuanced and precise movements.
- More channels: Sbus and Ibus can support up to 16 channels of data, giving you more options and more precise control over your remote-controlled device.
- Reduced wiring: By reducing the number of wires needed to send data, Sbus and Ibus help to reduce clutter on your RC vehicle and make it easier to install and maintain the wiring between the receiver and other components.
The Difference Between Sbus and Ibus
While both protocols are designed to send multiple channels of digital data over a single wire, their specifications and outputs can differ depending on the manufacturer. Sbus is developed by Futaba, while Ibus is developed by Flysky and iRangeX. Typically, Sbus has a higher data transmission rate and is more commonly found in high-end RC systems. On the other hand, Ibus is a more cost-effective option while still providing adequate performance for most RC applications.
Sbus and Ibus Compatibility
While Sbus and Ibus are not compatible with each other out of the box, some manufacturers have developed receivers that can translate the signals between the two protocols. This allows you to use an Sbus transmitter with an Ibus receiver, or vice versa, giving you more options for setting up your remote control equipment. It’s always important to check the compatibility between your transmitter and receiver before purchasing, however, to ensure that they are compatible with the protocols you want to use.
| Sbus | Ibus | |
|---|---|---|
| Transmission Rate | Up to 100kbps | Up to 18.5kbps |
| Channels | Up to 16 | Up to 14 |
| Compatibility | Compatible with Sbus transmitters and some Ibus receivers with a translator | Compatible with Ibus transmitters and some Sbus receivers with a translator |
In conclusion, Sbus and Ibus are both effective protocols for sending multiple channels of digital data over a single wire. By enabling more channels, reducing clutter, and providing higher resolution control, these protocols are revolutionizing the way people control their RC systems. While Sbus and Ibus have different specifications and compatibilities, they both offer benefits making them excellent options depending on your needs and budget.
Benefits of Sbus and Ibus
When it comes to radio communication between receivers and transmitters in unmanned aerial vehicles (UAVs), two digital protocols are commonly used: Sbus and Ibus. While they share some similarities, there are some key distinctions between the two. Here, we explore the advantages and benefits of both:
- Sbus – This protocol stands for “serial bus” and is a digital communication protocol used for drone receivers and transmitters that allow for faster data transfer rates. It enables the transmission of up to 16 control channels over a single signal cable, which allows for less cluttered wiring and a cleaner setup. Sbus also has the advantage of reduced latency, meaning that the response time between the transmitter and receiver is almost instantaneous, allowing for the drone to react faster to the commands given by the pilot. Additionally, Sbus receivers typically have higher precision and resolution, which allows for finer control over the drone and better stability during flight.
- Ibus – This protocol stands for “intelligent bus” and is a communication protocol developed by Flysky for their range of drone receivers and transmitters. Ibus uses a digital signal format for data transfer, which allows for faster and more accurate data transmission between the receiver and the transmitter. One advantage of Ibus is that it enables the transmission of up to 18 control channels over a single signal cable which is an improvement over traditional PWM (pulse width modulation) control. Ibus is compatible with Flysky transmitters, which means that it is ideal for those who use Flysky transmitters as their primary control mechanism.
Sbus vs. Ibus: Which is Better?
Both Sbus and Ibus have their own unique benefits and depending on what you require for your drone, one may be beneficial over the other. However, it is worth noting that both protocols have earned a reputation for being reliable and efficient, which is why they are the two most widely used digital communication protocols in drone technology today.
Ultimately, the use of either Sbus or Ibus can improve the overall performance of your drone, especially if you are looking for faster data transfer rates and short response times between control commands. It’s important to consider your own requirements as well as the compatibility of the protocol with your transmitter and receiver when making your choice.
Take some time to experiment with both protocols and decide which one works best for you. By considering the benefits of each, you can choose the right protocol to achieve optimal drone performance.
Sbus and Ibus Comparison Table

|---|---|---|---|---|---|
| Sbus | Serial Bus | Up to 16 | Works with most receivers and transmitters | Low | High |
| Ibus | Intelligent Bus | Up to 18 | Compatible with Flysky receivers and transmitters | Low | High |
Overall, Sbus and Ibus are two excellent communication protocols that offer significant benefits. Depending on your individual needs, one may be more advantageous than the other. Ultimately, it’s worth experimenting with both to see which one is a better fit for your drone and controller setup.
Limitations of Sbus and Ibus
While both Sbus and Ibus have their unique advantages, they also come with their limitations. It is essential to understand the limitations before deciding on which protocol to use for your setup.
- Compatibility: Sbus is only compatible with devices that can handle the Sbus signal. This limits the types of devices that can be used with Sbus. On the other hand, Ibus is more widely compatible, making it a more versatile protocol.
- Distance: Depending on the setup, Sbus signals may not travel as far as Ibus signals. This means that if you have a large setup, you may need to use more receivers to cover the same distance when using Sbus. Ibus, on the other hand, has a longer range, making it more suitable for larger setups.
- Bandwidth: Sbus has a limited bandwidth, which means that it can only transmit a limited number of channels. This can cause problems if you need to control a large number of devices that require more channels. On the other hand, Ibus has more bandwidth, making it more suitable for setups with a large number of devices.
Compatibility and Range are Key Limitations
Compatibility and range are two of the main limitations of Sbus and Ibus. Sbus is limited in terms of compatibility due to its restriction to devices that can handle the Sbus signal. This can be an issue if you have a specific device in mind that does not support Sbus. Similarly, Sbus signals may not travel as far as Ibus signals, which can be a problem if you have a large setup that requires signals to travel long distances.
Ibus is more versatile and can be used with a wider range of devices. It also has a longer range, making it more suitable for larger setups. Its ability to transmit signals over a longer distance means that you may not need to use as many receivers, which can save time and money. However, Ibus is not immune to limitations, and it has its issues that you need to be aware of.
The Bandwidth Limitation of Sbus
Another significant limitation of Sbus is its limited bandwidth. Sbus can only transmit a limited number of channels, which can be a problem if you need to control a large number of devices that require more channels. This can limit the types of devices that you can use with Sbus, making it less suitable for more complex setups.
| Protocol | Compatibility | Range | Bandwidth |
|---|---|---|---|
| Sbus | Limited | Shorter Range | Limited |
| Ibus | More Compatible | Longer Range | More Bandwidth |
Ultimately, the choice between Sbus and Ibus depends on your specific needs. It is essential to evaluate the pros and cons of each protocol carefully. Take into account the limitations that come with each, and choose the protocol that will provide the best performance for your setup.

Hopefully, this guide has helped you understand the differences between Sbus and Ibus and make a more informed decision about which protocol to use for your drone. Happy flying!
How Sbus and Ibus work
Both Sbus and Ibus are digital communication protocols used by remote control receivers to communicate with flight controllers in drones, planes, and other radio-controlled models. Each protocol has its own unique advantages and disadvantages.
- Sbus stands for Serial Bus and is developed by Futaba, a Japanese company known for its RC products. It is a unidirectional protocol that sends data from the receiver to the flight controller using one wire. Sbus allows for a faster and more precise transmission of data, reducing latency and enhancing flight control.
- Ibus, on the other hand, is a protocol developed by FlySky, a Chinese company. It is also a unidirectional protocol that uses one wire to send data from the receiver to the flight controller. Ibus is a more recent protocol but is quickly gaining popularity due to its affordable price and compatibility with FlySky products.
When using Sbus or Ibus, the PWM signals used in traditional analog RC systems, in which each channel requires its own wire, are no longer necessary. Instead, the receiver converts the analog signals to digital signals and sends them to the flight controller in one stream of data, increasing the accuracy and precision of the control system.
One significant advantage of using a digital communication protocol like Sbus or Ibus is the ability to connect multiple channels to a single wire, reducing wire clutter and simplifying the setup process. Another advantage is the ability to detect errors and lost signals, helping to prevent crashes and increase safety.
| Protocol | Manufacturer | Number of Channels | Latency (ms) |
|---|---|---|---|
| Sbus | Futaba | Up to 18 | 9.4 |
| Ibus | FlySky | Up to 14 | 14.6 |
As shown in the table above, Sbus has a lower latency than Ibus, but both protocols have a significantly lower latency than traditional analog RC systems. This reduction in latency allows for a more responsive and precise control of the model, which is essential for complex maneuvers and acrobatic flying.
Sbus and Ibus in the context of RC aircraft
In the world of remote-controlled aircraft, both Sbus and Ibus are frequently used communication protocols, and are used for different purposes.
- Sbus: Sbus is a serial communication protocol used to transfer control signals from the receiver to the flight controller, and from the flight controller to the motor controllers. With Sbus, multiple channels of information can be sent over a single wire, making it a space-saving option. Sbus also has a lower latency than traditional PWM signals, meaning it can provide faster, more responsive control to the aircraft.
- Ibus: Ibus is a similar protocol to Sbus, but it is used for transferring information from the receiver to the flight controller only. It is often used when space on the aircraft is at a premium, as it only requires a single signal wire and a ground wire. However, this compactness comes at the cost of being unable to transfer as much information as Sbus, although it still has lower latency than PWM signals.
So, when choosing between Sbus and Ibus for your RC aircraft, it’s important to consider your specific needs. If you require fast, low-latency control signals for both your flight controller and motor controllers, then Sbus is likely the better choice. However, if you have limited space on your aircraft and only need to transfer control signals from the receiver to the flight controller, then Ibus may be the better option for you.
The pros and cons of Sbus and Ibus
While both Sbus and Ibus provide certain benefits, they also have their downsides.
Sbus Pros:
- Can transfer multiple channels of information over a single wire
- Provides fast, low-latency control signals
- Easy to set up and configure
Sbus Cons:
- Requires a dedicated Sbus port on your flight controller
- May not be compatible with all flight controllers and motor controllers
- Requires a special Sbus signal decoder to convert the signal to usable PWM signals for servos and other devices that don’t support Sbus
Ibus Pros:
- Requires only a single signal wire and ground wire
- Provides low-latency control signals
- Simple and easy to set up and use
Ibus Cons:
- Can transfer only a limited amount of information
- May not be compatible with all flight controllers and motor controllers
- Requires a special Ibus signal decoder to convert the signal to usable PWM signals for servos and other devices that don’t support Ibus
Sbus and Ibus considerations when using telemetry systems
Another factor to consider when deciding between Sbus and Ibus for your RC aircraft is telemetry. Telemetry systems allow you to monitor various aspects of your aircraft’s performance in real-time, such as battery voltage, motor RPM, and GPS location. Sbus and Ibus both have telemetry capabilities, but they work differently.
Sbus uses a separate channel for telemetry data, meaning it doesn’t interfere with your control signals. Ibus, on the other hand, piggybacks telemetry data onto one of the control channels, meaning it reduces the number of available channels you have for controlling your aircraft. However, since Sbus requires a dedicated port on your flight controller, some telemetry systems may not be compatible with it.
| Sbus | Ibus | |
|---|---|---|
| Number of channels | Up to 16 | Up to 14 |
| Telemetry | Uses separate channel | Piggybacks on control channel |
| Latency | Lower than traditional PWM signals | Lower than traditional PWM signals |
| Compatibility | Requires dedicated Sbus port on flight controller | Can be used with any port that supports serial communication |
Ultimately, the choice between Sbus and Ibus depends on your specific needs and preferences. However, both protocols are widely used and proven to be reliable in the world of remote-controlled aircraft. With the right setup and configuration, you can achieve fast, low-latency control of your aircraft, as well as access to useful telemetry data.
