CRSF / PWM / SBUS / PPM Protocol Converter Module – RC Signal Adapter

Expand compatibility between RC transmitters, receivers, flight controllers, and control systems with this compact protocol conversion module. Designed for FPV, RC aircraft, UAV, and robotics applications, it converts supported control signals in real time with effectively zero additional latency.

The module supports automatic conversion between CRSF, PWM, SBUS, and PPM protocols, allowing integration between modern and legacy control systems without replacing existing hardware. Multiple output formats are available simultaneously depending on the selected input protocol, making it ideal for adapting radio equipment across different ecosystems.

Operating from a wide DC 5–18V input range and featuring configurable channel mapping and SBUS inversion options, the module offers a flexible solution for signal bridging and system integration.

Signal Conversion Modes:

• CRSF input → 8CH PWM + 16CH SBUS + 8CH PPM output
• PWM input → 16CH CRSF + 16CH SBUS + 8CH PPM output
• SBUS input → 16CH CRSF + 8CH PWM + 8CH PPM output
• PPM input → 16CH CRSF + 8CH PWM + 16CH SBUS output

Features:

• Automatic protocol conversion between CRSF, PWM, SBUS, and PPM
• Real-time signal conversion with minimal latency
