SBUS til RS232 Konverter RS232 til SBUS
SBUS → RS232 / RS232 → SBUS Converter Board
For UAV, UGV, USV Telemetry & Long-Range Remote Control Systems
Oversigt
Denne SBUS to RS232 or RS232 to SBUS directional converter board is a customized professional solution designed for unmanned systems such as Uavs, på UGV, USVs, and robotic platforms.
It enables reliable conversion between non-standard SBUS remote control signals og standard serielle kommunikationsprotokoller (RS232 eller UART-kompatibel serie).
Modulet løser fuldt ud det langvarige problem med SBUS-inkompatibilitet med computere, MCU'er, telemetri radioer, og netværksenheder, lave SBUS-data direkte anvendelig som en standard seriel grænseflade uden at kræve, at brugerne håndterer kompleks protokolparsing.
Dette produkt er meget udbredt i:
-
Langrækkende drone fjernbetjening
-
Trådløs telemetriudvidelse
-
Jordrobotstyring
-
Fjernnetværk til køretøjer
-
Industriel automation med RC-indgang


Technology Highlights
Avanceret protokolsupport (Opgraderet version)
-
Understøtter fuldt ud SBUS2 protokol
-
Bagudkompatibel med Sbus
-
Kompatibel med WBUS (SkyRC / Tiandi Fei)
-
Kompatibel med DE GÅR (FlySky)
Dette betyder selv de nyeste SBUS2-modtagere kan afkodes korrekt, at sikre langsigtet kompatibilitet.
Why SBUS Cannot Be Used Directly
SBUS er en digital kontrolprotokol oprindeligt udviklet af Futaba.
Selvom det ligner UART, det er ikke en standard seriel protokol.
SBUS Characteristics:
-
Baud rate: 100 kbps
-
Data format: 1 start bit, 2 stop bits, jævn paritet
-
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 stop bits, jævn paritet)
-
Limited compatibility
-
High risk of packet loss
-
Anbefalede only for special testing purposes
2. Adjustable Baud Rate Version (Highly Recommended)
-
Converts SBUS to standard serial baud rates:
-
9600
-
38400
-
57600
-
115200
-
-
Standard format:
-
1 start bit
-
1 stop lidt
-
No parity
-
-
Much lower error rate
-
Compatible with most MCUs, radios, and computers
3. Adjustable Baud Rate + Adjustable Frame Rate
SBUS frames:
-
25 bytes per frame
-
Default frame interval: 7–15 ms
Many telemetry radios, wired links, and wireless networks cannot handle such high frame rates, causing:
-
Buffer overflow
-
Packet loss
-
System freeze
Our module allows frame interval adjustment:
-
Adjustable from 20 ms til 500 Frk
-
14 selectable levels
-
Optimeret til:
-
Long-range telemetry radios
-
4G / LTE / IP networks
-
Wireless bridges
-
4. Adjustable Baud Rate + Integrated SBUS Encode / Decode
Without Encoding:
-
Users must manually pack 16 channels into SBUS
-
Requires:
-
Bit shifting
-
Frame timing control
-
Packet loss detection
-
Complex validation
-
-
High CPU usage
-
Risk of:
-
Control jitter
-
Signal instability
-
UAV loss of control
-
With Integrated Encode / Decode (Anbefalede):
-
Module handles:
-
SBUS decoding
-
Channel extraction
-
SBUS re-encoding
-
-
Adds checksum mechanism (XOR)
-
Ensures data integrity over:
-
Wireless links
-
Long-distance cables
-
Network transmission
-
-
Greatly improves system safety
