DSMX SRXL2 Serial Receiver with (SPM4651T)

DSMX SRXL2 serial receiver is a compact, 2.4 GHz DSMX device designed to deliver fast, low-latency control data and full telemetry through the SRXL2 serial protocol. It pairs with a Spektrum transmitter to extend link range and channel capacity, supporting up to 20 channels for complex flight setups. The unit includes a bind button for easy binding without a separate plug, dual diversity antennas for reliable signal, and a wide input voltage range from 3.3 to 8.4 volts. A low-noise amplifier helps reduce interference and maximize the control link range.

SRXL2 is a fast, open protocol that enables bi-directional telemetry and flight-control configuration from the transmitter to the flight controller over a single signal wire. The receiver is small and lightweight—ideal for helis, multi-rotors, and FPV builds—and features dual antennas for solid signal and longer coax antennas to maximize reception in installations where carbon fiber, metal, or battery packs shield the antenna. Operating with DSMX 2.4 GHz, it delivers extended range with minimal interference.
