FrSky RX4R 4/24CH PWM Receiver with Smart Port & SBUS - ACCESS Protocol

This receiver comes pre-flashed with FrSky's new ACCESS Protocol so it's ready to be used straight away with radios like the X9 Lite and Taranis X-Lite Pro

The RX4R / RX6R is a traditional PWM pin type receiver with SBUS support and we are now selling it pre-flashed with the new ACCESS protocol. There are two versions of the receiver, the RX4R has 4 PWM channels and the RX6R has 6 PWM channels.

About ACCESS protocol: Radio control systems use what's called an TX protocol to carry the signal from the radio to the receiver, think of it like a language. Previously FrSky's protocol was ACCST and you'll see this printed on it's radios and receivers. Recently, Frsky have developed a new protocol called ACCESS, which stands for Advanced Communication Control, Elevated Spread Spectrum. ACCESS is the upgrade of ACCST and brings with it a lot of new features, but they aren't interchangeable so you must use a ACCESS transmitter with a receiver that operates ACCESS also.

Features:

• Small and High sensitivity (40% increase of the range compared to previous X series receivers)
• Higher precision PWM and Low latency PWM output
• Lower power consumption
• Redundancy function supported
• Smart Port enabled and telemetry data transmission supported
• Battery voltage detection supported
• 2 detachable IPEX 4 connector antennas
• PCB protection with the comformal coating craftwork
