The 8CH PWM PPM SBUS Signal Conversion Module is a 32-bit MCU-based interface adapter designed to bridge legacy and modern RC protocols. It automatically identifies and converts between PWM, PPM (CPPM), and SBUS signals, enabling cross-compatibility between standard servos/ESCs and advanced flight controllers or DJI Wizard systems.

Features

  • 32-bit MCU for automatic signal identification and conversion between PWM, PPM, and SBUS protocols.
  • Wide voltage input range (3.7V to 8.4V, tolerant up to 20V) with low operating current (<30mA).
  • Dedicated channels for simultaneous input and output, including a specific channel for PPM/SBUS input and output.
  • Enables use of DJI Wizard remotes with standard PWM-based aircraft and servos.
  • Compact footprint (29mm x 26mm) and lightweight (5g) design for easy integration into builds.

Description

This signal conversion module serves as a critical interoperability bridge in multirotor and fixed-wing RC systems. Its core function is to translate control signals between the legacy PWM standard used by most ESCs and servos and the serial protocols (PPM and SBUS) utilized by modern flight controllers and advanced radio systems like the DJI Wizard. The integrated 32-bit microcontroller handles signal processing and automatic protocol detection, eliminating the need for manual configuration switches.

Engineered for robust integration, the module features a wide-voltage power design that accepts direct power from a receiver (3.7V-8.4V) and is tolerant of inputs up to 20V, protecting against voltage spikes. Its channel mapping allows flexible routing, with channels 1-8 dedicated to PWM I/O, channel 9 for PPM/SBUS input or PPM output, and channel 10 for SBUS or PPM output, facilitating complex signal chain setups.

Key Features

  • Automatic Signal Identification: 32-bit MCU detects input signal type (PWM, PPM, SBUS) without manual switching.
  • Bidirectional Protocol Conversion: Converts PWM to/from serial SBUS and PPM (CPPM) signals.
  • Cross-Platform Compatibility: Enables DJI Wizard remote controls to operate standard PWM-based aircraft and servos.
  • Robust Power Design: Wide operating voltage (3.7V-8.4V) with high tolerance (up to 20V) and low current draw (<30mA).
  • Simultaneous Multi-Protocol Operation: Can process PWM input while outputting both PPM and SBUS signals concurrently.
  • Compact and Lightweight: Minimal footprint and weight (5g) for seamless integration into tight drone and plane builds.

Applications

  • Integrating DJI Wizard or other SBUS-based remote control systems into legacy PWM-based quadcopter or fixed-wing aircraft.
  • Adding serial (SBUS/PPM) control capability to traditional RC planes or helicopters using standard PWM receivers.
  • Creating a wired receiver simulator by converting a transmitter's PPM trainer port signal into standard PWM outputs for servos and ESCs.
  • Protocol bridging in complex FPV or drone builds where a flight controller requires SBUS input but the available receiver only outputs PWM.
  • Testing and development setups requiring flexible signal routing and conversion between different RC control standards.

Frequently Asked Questions

What is the primary function of this signal conversion module?

This module acts as a bidirectional protocol bridge, automatically converting remote control signals between standard PWM (used by most ESCs and servos) and the serial protocols SBUS and PPM (used by modern flight controllers and systems like DJI Wizard). It enables cross-compatibility between different generations of RC equipment without manual switching.

Can I power this module directly from my LiPo battery?

It is designed to be powered by the receiver's supply voltage, typically between 3.7V and 8.4V. While the module is tolerant of inputs up to 20V for protection, it is not recommended to connect it directly to a high-voltage LiPo source (e.g., 4S 16.8V) without a regulated BEC. Always power it from a stable 5V BEC or your receiver's regulated output.

How do I connect a DJI Wizard remote to a standard PWM-based drone?

Connect the SBUS output from your DJI Wizard air unit or receiver to the module's SBUS input (typically Channel 9). Then, connect the module's PWM output channels (1-8) to your drone's ESCs and servos. The module will convert the SBUS signal into individual PWM channels that your standard flight controller or direct ESC connections can understand.

Does this module support simultaneous input and output of different protocols?

Yes. Its channel architecture allows for flexible routing. For example, you can have PWM signals from a standard receiver input on channels 1-8, while the module simultaneously outputs a combined PPM or SBUS stream on Channel 9 or 10 to a flight controller that requires a serial input. The 32-bit MCU manages these conversions in real-time.
