Convertitore da SBUS a RS232 da RS232 a SBUS

SBUS → RS232 / RS232 → SBUS Converter Board

For UAV, UGV, USV Telemetry & Long-Range Remote Control Systems

Panoramica

Questo SBUS to RS232 or RS232 to SBUS directional converter board is a customized professional solution designed for unmanned systems such as UAVS, all'UGV, USVs, and robotic platforms.
It enables reliable conversion between non-standard SBUS remote control signals e standard serial communication protocols (RS232 or UART-compatible serial).

The module fully solves the long-standing problem of SBUS incompatibility with computers, MCUs, telemetry radios, and network devices, making SBUS data directly usable as a standard serial interface without requiring users to handle complex protocol parsing.

This product is widely used in:

• Long-range drone remote control

• Estensione telemetria wireless

• Ground robot control

• Remote vehicle networking

• Industrial automation with RC input

Technology Highlights

Advanced Protocol Support (Upgraded Version)

• Fully supports SBUS2 protocol

• Backward compatible with SBUS

• Compatibile con WBUS (SkyRC / Tiandi Fei)

• Compatibile con VANNO (FlySky)

This means even the latest SBUS2 receivers can be decoded correctly, ensuring long-term compatibility.

Why SBUS Cannot Be Used Directly

SBUS is a digital control protocol originally developed by Futaba.
Although it looks similar to UART, it is not a standard serial protocol.

SBUS Characteristics:

• Baud rate: 100 kbps

• Data format: 1 iniziare un po', 2 bit di arresto, addirittura parità

• Inverted logic level

• Packed bit-level channel data (11 bits per channel)

Because of this:

• Most MCUs and computers cannot read SBUS directly

• Even if 100k baud is supported, error rates are extremely high

• No built-in checksum in standard SBUS

• Not suitable for long-distance wired or wireless transmission

---

What Our Module Does

Our converter module:

• Converts SBUS electrical levels → standard logic levels

• Converts non-standard SBUS frames → standard serial data

• Decodes SBUS into directly usable integer channel values

• Optionally re-encodes data back into SBUS format

After conversion, SBUS can be treated like a normal serial port, allowing developers to focus on application logic instead of protocol complexity.

Product Variants & Functional Options

1. 100k Transparent Transmission Version (Not Recommended)

• Outputs raw SBUS format (100k baud, 2 bit di arresto, addirittura parità)

• Limited compatibility

• High risk of packet loss

• Consigliato solo per scopi di test speciali

---

2. Adjustable Baud Rate Version (Highly Recommended)

• Converte SBUS in velocità di trasmissione seriale standard:

  • 9600

  • 38400

  • 57600

  • 115200

• Formato standard:

  • 1 iniziare un po'

  • 1 fermati un po'

  • Nessuna parità

• Tasso di errore molto più basso

• Compatibile con la maggior parte degli MCU, radio, e computer

---

3. Adjustable Baud Rate + Adjustable Frame Rate

Cornici SBUS:

• 25 byte per fotogramma

• Intervallo frame predefinito: 7–15 ms

Molte radio telemetriche, collegamenti cablati, e reti wireless non è in grado di gestire frame rate così elevati, causando:

• Overflow del buffer

• Perdita di pacchetti

• Blocco del sistema

Il nostro modulo lo consente regolazione dell'intervallo dei fotogrammi:

• Regolabile da 20 ms a 500 SM

• 14 livelli selezionabili

• Ottimizzato per:

  • Radio telemetriche a lungo raggio

  • 4sol / LTE / Reti IP

  • Ponti wireless

---

4. Adjustable Baud Rate + Integrated SBUS Encode / Decodificare

Without Encoding:

• Gli utenti devono imballare manualmente 16 canali in SBUS

• Richiede:

  • Un po' in movimento

  • Controllo della temporizzazione dei fotogrammi

  • Rilevamento della perdita di pacchetti

  • Convalida complessa

• Utilizzo elevato della CPU

• Rischio di:

  • Controllare il jitter

  • Instabilità del segnale

  • Perdita di controllo dell'UAV

With Integrated Encode / Decodificare (Consigliato):

• Maniglie del modulo:

  • Decodifica SBUS

  • Estrazione del canale

  • Ricodifica SBUS

• Aggiunge meccanismo di checksum (XOR)

• Garantisce l'integrità dei dati:

  • Collegamenti senza fili

  • Cavi a lunga distanza

  • Trasmissione in rete

• Greatly improves system safety
