The Bidirectional USB to SBUS / SBUS to USB Converter is a professional interface module designed for RC, İHA, robotik, ve endüstriyel kontrol uygulamaları.
It provides a bridge between SBUS receivers, USB computers, mikrodenetleyiciler, and UART-based devices, allowing users to easily exchange control signals and channel data between different systems.
Unlike simple USB-UART converters, this module is specially designed for SBUS communication. It handles:
- SBUS signal level conversion
- SBUS protokolü ayrıştırma
- UART iletişim dönüşümü
- Çerçeve zamanlama kontrolü
- Optional SBUS encoding and decoding
- Data integrity verification
Dönüşümden sonra, users can treat SBUS communication like a standard serial interface without dealing with complicated SBUS protocol details.

Why Is an SBUS Converter Needed?
Understanding SBUS Protocol
SBUS is a digital RC communication protocol originally developed by Futaba.
Although SBUS is similar to UART, it is not a standard UART communication format.
Standard SBUS parameters:
- Baud hızı: 100 kbps
- Başlangıç biti: 1
- Bitleri durdur: 2
- Eşit eşitlik
Most computers, mikrodenetleyiciler, and serial applications cannot directly process this format.
Problems include:
- Unsupported baud rate
- Incorrect timing
- Communication errors
- High data loss rate
What Does Our Converter Solve?
The module performs three important functions:
1. Electrical Signal Conversion
Converts SBUS electrical signals into normal UART logic levels.
2. Protocol Conversion
Converts the special SBUS communication format into standard UART:
Supported UART baud rates:
- 9600
- 38400
- 57600
- 115200
Standard output format:
- 1 başlangıç biti
- 1 biraz dur
- Eşitlik yok
3. SBUS Data Processing
The module can automatically process SBUS frames.
Users do not need to write complicated SBUS parsing programs.
The module handles:
- Bit kaydırma
- Kanal çıkarma
- Frame synchronization
- Error checking
Configuration Options Explained
Different applications require different firmware configurations.
Please select the correct option before ordering.
Option 1: Basic SBUS Transparent Version
100K Baud Rate SBUS Transparent Transmission
This version keeps the original SBUS communication format.
Parameters:
- Baud hızı: 100 kbps

Important Note
100K baud rate is not a common UART speed.
Many MCUs and serial devices do not support it directly.
Please confirm compatibility before purchasing this version.
