Spectrum Serial SRXL2 receiver with telemetry

Spectrum Receiver Serial SRXL2 with telemetry utilizes the rich-function bidirectional Spectrum SRXL2 protocol, which provides fast and fast serial data connectivity with up to 20 channels and greatly improves bidirectional communication. The SPM4651T is small, lightweight and ideal for Heli, Multi-Rotor and FPV users. Thanks to two antennas it offers excellent range and performance without interference. The receiver uses the SRXL2 protocol, which supports telemetry (the telemetry data must therefore be provided by the control unit, the receiver itself only provides information about the quality of the received signal). There is a button on the receiver board for easy pairing and LED signaling.

The receiver is suitable for various control units in RC models, but also for industrial applications and robotics.

New Spectrum SRXL2 protocol

SRXL2 is a powerful communication protocol based on a rich feature-rich UART interface that supports bidirectional communication between the radio system and the flight controller. It supports telemetry and configuration of control unit parameters (Forward Programming, VTX Setup, and Text Gen Programming), one signal wire per unit. SRXL2 is not backward compatible with SRXL.

The SRXL2 protocol replaces the older SRXL protocol. SRXL2 is faster and safer. Developers are provided with source code supporting SRXL2 communication: www.srxl2.com

Small, light and powerful

The SPM4651 with a weight of only 3g is ready to be installed in most models with a controller with minimal space requirements.
