Spektrum SRXL2 Remote Serial Receiver with Telemetry

The SPM4651T DSMX SRXL2 Serial Micro Receiver takes the original SPM4649T receiver and adds more value, functionality, and a longer range for control and telemetry. The SPM4651T utilizes our feature-rich SRXL2 protocol to provide pilots with a fast serial data connection with up to 20 channels. SRXL2 is a powerful and open-source communication protocol developed by Spektrum. It significantly enhances bidirectional communication between the radio system and the flight controller, enabling additional telemetry functionalities and the configuration of the flight control directly from the pilot's Spektrum transmitter via a single signal cable.

The SPM4651T is small, lightweight, and ideal for helicopter, multirotor, and FPV enthusiasts. It also features a simple bind button, so pilots no longer need to carry a separate receiver or bind plug to bind. Dual antennas provide receiver diversity for a solid signal, and the long coaxial antennas help ensure maximum signal strength in all orientations for challenging installations where carbon fiber, metal, and batteries shield the antenna. With the Spektrum DSMX 2.4 GHz RF protocol, the Spektrum SRXL2 Serial Telemetry Receiver offers remarkable range and interference-free operation.
