Introduction to FrSky RX4R 4/24CH telemetry receiver, including 4 PWM outputs, extremely high precision and low latency, PWM output latency is 9ms less than that of X series receivers in high speed mode, redundancy function, another receiver can be added as a back-up
The FrSky RX4R is a high-precision telemetry receiver featuring 4 PWM outputs with low latency (9ms less than X series) and redundancy support. It operates under the ACCESS protocol and offers a range increase of up to 40% compared to previous models, suitable for applications requiring reliable signal transmission over distances greater than 2km.
