Overview
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.

Spektrum makes quality gear. This is another example.

I was happy to see an SPM4650 offered with the connector already soldered in place. I was not happy when it arrived and I discovered the cable that came with it was not the standard SRXL2 configuration. In the photo with the connectors wired differently, this is how the cable comes when you buy this. The second photo shows how the cable should look (both ends identical) when the 4650 is used a normal satellite Rx. It is easy to extract and rearrange the pins, but WHY it comes this way is a total mystery. Minus 1 star.
