Adjustable Frame Rate Control
SBUS normally sends data frames continuously with a short interval.
For USB, wireless links, or long-distance communication systems, excessive frame rates may cause:
- Desbordamiento del búfer
- Congestión de paquetes
- Pérdida de datos
The adjustable frame rate version allows users to configure the frame interval:
10ms – 500 ms
This improves compatibility with:
- Wireless serial links
- USB extension systems
- Long-distance control applications
Integrated SBUS Encoding & Descodificación (Opcional)
The codec version integrates SBUS protocol processing.

Preguntas frecuentes
q: Is this a USB to SBUS or SBUS to USB device?
A: It supports both directions. The module works as a bidirectional USB ↔ SBUS converter.
q: Can I connect an SBUS receiver directly to a PC?
A: Sí. The module converts SBUS signals into USB serial communication, allowing direct PC connection.
q: Does it support SBUS2?
A: Sí. The upgraded version supports SBUS2 protocol.
q: Which version should I choose?
- For simple SBUS monitoring: Basic Version
- For MCU/UART applications: Versión de velocidad de baudios ajustable
- For wireless or long-distance links: Frame Rate Control Version
- For professional UAV applications: Versión completa
q: Does the SBUS-to-USB converter output raw SBUS frames over a standard Linux serial interface?
A: Sí. The converter uses a CH340 USB-to-serial interface and appears as a standard virtual serial port on the computer.
In raw mode, the SBUS data is not decoded or modified. The data received from the SBUS input is output through the USB serial port as the original SBUS data stream. For standard SBUS, this means the original 25-byte SBUS frames are transmitted to the serial port.
It does not appear as a USB joystick or HID device.
q: Will the converter work with Linux?
A: Sí. The CH340 USB-to-serial interface supports Linux and other major operating systems. On many relatively recent Linux distributions, the required CH340 driver is already included in the Linux kernel. If the device is not automatically recognized, the appropriate CH340 driver can be installed manually.
Official WCH CH340 driver page: https://www.wch.cn/products/CH340.html
q: What device name will the converter use in Linux?
A: After the CH340 driver is recognized, the converter normally appears as a standard serial device, Por ejemplo: /dev/ttyUSB0
The exact device name may vary depending on the Linux system and the other USB devices connected.
q: Does the converter require a proprietary Linux driver?
A: No proprietary application or special interface is required. The converter uses the standard CH340 USB-to-serial interface.
If the Linux system already includes the CH340 driver, no additional driver installation is normally required. De lo contrario, the standard CH340 driver can be installed.
q: Can I parse the raw SBUS frames myself?
A: Sí. This is supported in the raw-data mode.
The converter passes the SBUS input data directly to the USB serial interface, allowing your own Linux software or simulator to read and parse the original SBUS frames.
q: Does the converter decode SBUS channels internally?
A: It can support different output modes depending on the product configuration. For applications that require the original SBUS data, use the raw mode. In this mode, the output consists of the original 25-byte SBUS frames. A separate decoded-data mode can output a 35-byte data stream, but this is not required when your software needs to parse the original SBUS frames itself.
q: Is a Linux GUI debugging application provided?
A: We currently provide a Windows debugging/configuration tool. A dedicated Linux GUI application is not currently provided. Sin embargo, this is generally not necessary for applications that only need to access the SBUS data, because the converter operates as a standard USB serial device under Linux.
q: Should I choose the version with the built-in SBUS decoder?
A: It depends on your PC software. If you develop your own PC application, recomendamos el version with the built-in decoder. It outputs decoded SBUS data in a 35-byte format, making it easier for your software to process. If you use a third-party PC application, recomendamos el version without the built-in decoder, because third-party software may require the original SBUS protocol data.
q: Can the built-in decoder be disabled?
A: No. The decoder is integrated into the chip and is permanently configured during chip manufacturing. Users cannot enable or disable the decoder through software.
q: What is the difference between the decoder and non-decoder versions?
A: SBUS is a compressed protocol. El non-decoder version outputs the original SBUS protocol data, while the decoder version automatically decodes the data and outputs the decoded 35-byte data format.
q: Why is the baud rate adjustable?
A: The adjustable baud rate is designed to help reduce data errors that may occur at the standard 100 kbps baud rate. Users can select a suitable baud rate according to their application and communication environment.
q: Why is the frame rate adjustable?
A: The adjustable frame rate helps solve serial data sticking or packet concatenation problems on the PC side. Adjusting the frame rate can make the received serial data easier for PC software to process correctly.
q: Which version should I choose?
A:
| PC Software | Versión recomendada |
|---|---|
| Your own/custom PC application | Built-in Decoder |
| Third-party PC application | Without Decoder |
| Need original SBUS protocol data | Without Decoder |
| Need decoded 35-byte data directly | Built-in Decoder |
