Futaba SBD-3 Single Channel S.Bus Servo Decoder Lead

The Futaba SBD-3 Single Channel S.Bus Servo Decoder is a specialized interface cable designed to integrate a single conventional (non-S.Bus) servo into an S.Bus or S.Bus2 system. Unlike the larger SBD-2, which provides eight ports, the SBD-3 is a compact, lightweight "lead-style" decoder. This makes it the ideal solution for adding one specific analog or digital servo to a digital network without the weight or bulk of a multi-port hub, perfect for tight spaces like small gliders, park flyers, or complex scale aircraft.

Key Features:

• Single-Channel Conversion: Transparently converts the S.Bus digital data stream into a standard PWM signal for one conventional servo.
• Compact & Lightweight: The inline design weighs significantly less than traditional decoders, allowing it to be tucked inside wings or narrow fuselages easily.
• S.Bus & S.Bus2 Compatible: Works seamlessly with all modern Futaba S.Bus systems, allowing you to utilize high-channel counts through a single receiver port.
• Programmable Channel Assignment: The specific channel the SBD-3 responds to (e.g., Channel 1 through 18) can be easily programmed using a Futaba CIU-2/CIU-3 USB interface or directly through the S.Bus menu on high-end Futaba transmitters.
• High Voltage (HV) Support: Capable of handling up to 8.4V, ensuring compatibility with modern LiPo-powered radio systems and HV servos.

Application Tip:

The SBD-3 is incredibly useful for "retrofitting" an older, high-quality analog servo into a modern S.Bus setup. However, remember that the SBD-3 does not come with a pre-assigned channel out of the box. You will need a Futaba transmitter with an S.Bus setting port or a CIU-3 USB adapter to tell the lead which channel it should "listen" to before installation.
