The Spektrum SPM4650 DSMX SRXL2 serial micro radio receiver is designed to be used with FPV drones. This receiver provides more value, functionality and fly-by telemetry while decreasing the size and weight of the already micro-sized Spektrum serial receiver.

 

The SPM4650 uses Spektrum's feature-rich SRXL2 protocol to give pilots a blazing fast serial data connection with up to 20 channels. SRXL2 is a powerful communication protocol that improves bi-directional communication between the radio system and flight controller for added telemetry functionality and flight control configuration right from the pilots' Spektrum Transmitter, all over one signal wire.
