Description:
8-Channel PPM Encoder Module Flight Controller Adapter is a compact and reliable interface designed to convert multiple PWM signals from a standard RC receiver into a single PPM signal compatible with supported flight controllers and autopilot systems. It provides a convenient solution for connecting conventional PWM-output receivers to flight controllers that accept a combined PPM input.
The module accepts up to 8 individual PWM channels from an RC receiver and combines them into one PPM output channel. This simplifies receiver-to-flight-controller wiring by reducing multiple signal connections to a single PPM connection. No modification of the RC receiver is required, making installation easier for drone builders, RC hobbyists, and robotics enthusiasts.
The PPM Encoder Module is suitable for use with compatible flight controllers such as Pixhawk, APM, PX4, CC3D, MultiWii, MWC, PPZ, MK, and racing F3-based systems, depending on the specific controller's PPM input compatibility. It is particularly useful in multirotor, fixed-wing, RC aircraft, and custom autopilot projects where a PPM signal is required.
The module comes pre-flashed with firmware, providing a plug-and-use solution without requiring users to program or configure the encoder firmware before installation. Its compact design and dedicated PWM and PPM cables make it practical for integration into space-constrained RC electronics systems.
With an 8 PWM-channel input and single PPM-channel output, this encoder helps simplify signal management while maintaining stable operation and accurate signal conversion. It is a practical accessory for upgrading or integrating traditional RC receivers with modern flight-control platforms.
