USB to SBUS Converter | SBUS to USB Adapter with Adjustable Baud Rate

Short Description

Bidirectional USB to SBUS / SBUS to USB converter for RC receivers, flight controllers, robotics, and industrial control systems. Supports USB 2.0 virtual COM port communication, standard SBUS, SBUS2, IBUS and WBUS, with optional adjustable baud rate, frame rate control, SBUS encoding/decoding, and checksum verification.

USB to SBUS Converter / SBUS to USB Adapter

The USB to SBUS Converter is a bidirectional interface module designed to connect SBUS-based devices with PCs, microcontrollers, UART equipment, wireless data links, and industrial control systems.

It supports both SBUS to USB and USB to SBUS communication. The USB interface operates as a standard USB 2.0 CDC Virtual COM Port, allowing an SBUS receiver or control device to communicate with a computer without requiring a dedicated SBUS interface.

Different firmware configurations are available for simple transparent communication, adjustable UART baud rates, frame rate control, SBUS encoding/decoding, and data integrity verification.

How It Works

SBUS to USB

Connect an SBUS receiver or other compatible SBUS source to the converter. The module converts the SBUS communication into USB serial data, allowing a PC or other USB host to receive the control data through a virtual COM port.

USB to SBUS

The converter can also work in the opposite direction, converting USB UART data into SBUS output for compatible control systems and embedded applications.

Optional SBUS Decoding

The codec version can decode SBUS frames internally and output channel information instead of requiring the host controller to process the SBUS protocol.

The decoded data can contain:

• 16 channel values

• Channel values from 0–2047

• Status flags

• XOR checksum

Frequently Asked Questions

Can this adapter convert both USB to SBUS and SBUS to USB?

Yes. The module supports bidirectional USB ↔ SBUS communication. The available functions depend on the selected configuration.

Can I connect an SBUS receiver directly to a computer?

Yes. The SBUS-to-USB version converts the SBUS signal into USB serial communication through a virtual COM port.

What baud rates are supported?

The adjustable baud rate versions support 9600, 38400, 57600 and 115200 baud.

Does it support SBUS2?

An upgraded version supports SBUS2. Please confirm the required protocol before ordering.

How many SBUS channels are supported?

Standard SBUS frames contain 16 channels. The codec version can decode these channels into individual channel values.

Is frame rate adjustable?

Yes, on the frame-rate-control and full versions. The configurable frame interval is approximately 10–500 ms.
