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. It can also be used to interface traditional PWM, SBUS, and PPM radio systems with CRSF/ELRS-based control equipment (ELRS systems using CRSF protocol). 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 PWM channel selection, selectable SBUS inversion, status LED indication, and CRSF feedback with battery voltage monitoring, the module offers a flexible solution for signal bridging and system integration. PWM output defaults to channels 1–8 and can be switched to channels 9–16 by bridging the onboard jumper pads. SBUS operates as standard inverted SBUS by default and can be configured for non-inverted SBUS operation where required.
Signal Conversion Modes:
- PWM input → Outputs SBUS (inverted) + CRSF + PPM (real time)
- PPM input → Outputs SBUS (inverted) + CRSF + 8CH PWM (real time)
- SBUS input → Outputs CRSF + PPM + 8CH PWM (real time)
- CRSF input → Outputs SBUS (inverted) + PPM + 8CH PWM (real time)
