The SPM4650 DSMX SRXL2 Serial Micro Receiver takes the original SPM4648 receiver and adds more value, functionality and fly-by telemetry, while decreasing the size and weight of the already micro sized Spektrum serial receiver. The SPM4650 uses our 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.
The SPM4650 is small, lightweight, and customizable, providing an excellent receiver for even the smallest of applications. 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 solid signal and the long coax antennas help to provide maximum signal strength in all orientations for challenging installations where carbon fiber, metal and batteries shield the antenna. And with Spektrum DSMX 2.4GHz RF protocol the Spektrum SRXL2 Serial Micro Receiver provides remarkable range and interference free performance.
The SPM4650 employs an advanced antenna diversity system that provides optimal range, RF performance, and polarization. All supported by 2 long coaxial antennas that are perfect for FPV, Multirotor and Heli pilots with metal and carbon fiber abundant models.
No bind plug? No Problem! The SPM4650 is the most convenient to bind Spektrum serial receiver yet, simply press the bind button at any time, before or after power is applied, and the SPM4650 is in bind mode. And like other Spektrum serial receivers, users can also bind using a supported flight controller and computer, but now there is no need to power cycle!
This Reciever is not comatilble with the following aircraft:
When connected to a Spektrum Smart charger, unique parameters and health of your Smart LiPo battery upload from the Smart memory microchip integrated into the battery. Through the charger, you can set and record preferred settings, such as charge rates, so that all you have to do to charge the pack is press the "start" button. Smart technology will take care of the rest. Every Smart LiPo battery is factory assembled with the next-generation IC3™ and IC5™ output connector that utilizes a data transfer wire to relay saved information to your Smart Chargers.
An integrated microchip allows each Smart Battery to save vital information such as battery brand, chemistry, cell count, capacity, number of charging cycles, number of discharges, C rating, battery temperature, and internal resistance. Additionally, each battery will save a log of unhealthy events such as over-charge, over-discharge, and over-temperature. This allows you to make the most informed decision about each battery when you are getting your gear ready for a day at the field or the track
With an operating voltage range between 3.3v to 8.4v, users will no longer be constrained to which devices they can use to operate their serial receiver now that the limited voltage range is eliminated.
Fly-By Telemetry is a low range telemetry signal that is perfect for checking telemetry before and after a flight. And with SRXL2 Technology users will get even more telemetry data and transmitter to device programming support via Forward Programming, VTX Setup, and/or Text Gen Programming.
