Buy a reliable Radiolink R9DS receiver for your quadcopter and model aircraft!
Provide your drone with stable communications at record distances. The Radiolink R9DS receiver operates in the 2.4 GHz band and uses hybrid DSSS and FHSS spread spectrum technology, which guarantees high noise immunity and signal stability. The device is capable of providing reliable reception at a distance of up to 4000 meters in line-of-sight conditions.
It is an ideal choice for racing drones, FPV aircraft and multicopters where every second counts.
-
Record range. Up to 4000 meters provides reliable communication at extreme distances.
-
Hybrid spectrum DSSS/FHSS. The two spread spectrum technologies operate synchronously to provide maximum noise immunity.
-
Two operating modes. Supports 9 PWM channels (red LED) or 10 SBUS/PWM channels (blue LED).
-
Built-in telemetry. Transmits signal strength and receiver voltage data, and also supports external PRM modules.
-
Compact size and light weight. Dimensions 43x24x15 mm and a weight of only 11-14 grams allow it to be installed in any model.
Operating principle and connection versatility
The Radiolink R9DS receiver is compatible with the popular AT9, AT9S, AT10 and AT10II transmitters. It supports two output modes, which can be switched by pressing the ID SET button twice. In PWM mode, the red LED indicates the operation of 9 channels.
In SBUS mode, the blue LED activates the 10-channel mode, with channel 9 producing the SBUS signal, and channels 1 to 4 duplicating the PWM signals of channels 7-10. This allows you to use just one wire to connect to the flight controller, saving weight and simplifying assembly.
The receiver is equipped with built-in telemetry sensors that transmit information about voltage and signal level to the remote control. When using additional modules PRM-01 or PRM-02, you can receive data on GPS, speed, altitude and other parameters directly on the transmitter screen. The positioning accuracy is 4096 steps with a pulse width of 0.25 µs, which guarantees smooth and accurate operation of the servos.
