Spektrum SPM4651T DSMX SRXL2 Serial Receiver with Telemetry

The Spektrum® SPM4651T is a DSMX SRXL2 serial receiver with telemetry, designed for pilots who want the simplicity of a single-wire digital connection and the insight of real-time telemetry data. SRXL2 is Spektrum’s advanced serial protocol — a single wire carries all channel data digitally to compatible ESCs, flight controllers, and other SRXL2-capable devices, eliminating the clutter of individual servo leads and reducing latency for faster, more precise response. The built-in telemetry capability sends real-time data — including voltage, signal strength, and other sensor data — back to your compatible Spektrum transmitter, so you always know what’s happening with your model during flight or a run.
