The Traxxas 6551X Telemetry GPS Module is an add‑on sensor that provides real‑time GPS‑based data for Traxxas Link™ telemetry systems. it captures information such as vehicle speed, distance, lap times, elevation, heading, and GPS‑based location, and transmits this data to a compatible Traxxas radio or smartphone app. the module integrates with the Traxxas Link wireless module and TQi radio systems, allowing drivers to monitor performance metrics while driving or reviewing sessions afterward. it mounts to the RC vehicle and uses the Traxxas power system for operation, making it a useful upgrade for users who want detailed performance feedback and tracking during racing, bashing, or trail runs.
