The SPM4650 DSMX SRXL2 Serial Micro Receiver builds on the original SPM4648 receiver with more functionality and fly-by telemetry while being smaller and lighter. It uses the SRXL2 protocol for a fast serial data connection with up to 20 channels, bi-directional communication, and flight controller configuration directly from a Spektrum transmitter over a single signal wire. Dual coaxial antennas provide diversity and signal strength in challenging installations. Note: SRXL2 is not backward compatible with SRXL protocol, and SRXL2 support updates are required for your device — see www.srxl2.com for details.
