Overview

The USB to SBUS / SBUS to USB Converter Module is a professional interface device designed to bridge RC SBUS signals and USB-based systems.

It allows:

• SBUS receivers to communicate directly with computers via USB

• USB devices or microcontrollers to output SBUS signals

• Transparent and decoded data exchange between USB UART and SBUS

Unlike simple SBUS adapters, this module fully handles the electrical level conversion, protocol translation, timing control, and optional SBUS encoding/decoding, making it suitable for both development and real-world control systems.

This solution is widely used in:

• UAV flight control development

• RC signal debugging

• Wireless telemetry extension

• Network and industrial control via USB UART

Features

✔ True USB to SBUS & SBUS to USB Conversion

• Bidirectional conversion between USB UART and SBUS

• Works as a USB serial device on PC

• Plug-and-play, no external USB cable required (direct USB Type-A version)

✔ Supports Multiple RC Protocols

• SBUS

• SBUS2

• IBUS

• WBUS (SkyRC / TianDiFei)

✔ Adjustable USB UART Baud Rate

Converts SBUS’s non-standard communication into standard USB serial speeds:

• 9600

• 38400

• 57600

• 115200

All outputs use standard UART format, fully compatible with:

• PCs

• Microcontrollers

• Data radios

• Network equipment with UART ports

✔ Adjustable Frame Rate (Critical for USB & Wireless Use)

• Output frame interval adjustable from 10 ms to 500 ms

• Prevents USB buffer overflow

• Ideal for wireless USB-to-serial bridges and long-distance transmission

✔ Integrated SBUS Encoding & Decoding (Optional)

With the codec version:

• SBUS is decoded into 16 independent channel values

• Each channel output as a direct integer (0–2047)

• No SBUS parsing required on the host side

✔ Data Integrity for USB and Wireless Transmission

• Standard SBUS has no checksum

• Codec version adds XOR checksum

• Greatly improves reliability over:

  • USB extenders

  • Wireless serial links

  • Long cables
