Description

The FrSky R-XSR Ultra Mini Receiver is the direct successor to the popular XSR, offering identical functionality in a package approximately one-third the size and weight. Its design prioritizes integration into space-constrained FPV racing drones and micro builds without sacrificing the full-range reception and telemetry capabilities of its larger counterparts.

Engineered with a focus on reliability, the R-XSR incorporates a redundancy function to enhance signal security. The unit features an IPEX connector for its antenna, allowing for easy replacement or customization of antenna placement to optimize signal reception in diverse flying environments. The receiver is firmware-upgradable, ensuring long-term compatibility with evolving FrSky protocols and features.

Key Features

  • Ultra-Compact Design: Dimensions of 16x11x5.4mm and a weight of 1.5g minimize impact on drone CG and fit in the most constrained frames.
  • 16-Channel SBUS/CPPM: Delivers high-resolution, low-latency control signals for complex aircraft setups.
  • Smart Port Telemetry: Enables real-time transmission of battery voltage, RSSI, and other flight data back to the transmitter.
  • ACCESS Protocol Ready: Flashing with ACCESS firmware enables advanced features like no-rebind registration and redundancy.
  • Replaceable IPEX Antenna: Allows for antenna customization, repair, or optimal positioning to mitigate signal shadowing.
  • Wide Voltage Input: 3.5V to 10V operating range provides direct compatibility with 1S LiPo up to 3S LiPo (via BEC) power systems.
  • Firmware Upgradable: Future-proofs the receiver against protocol updates and enables feature activation via FrSky's update tools.

Applications

  • Ultra-lightweight 3-inch and 5-inch FPV racing drones where every gram counts.
  • Compact freestyle and cinewhoop builds requiring a reliable telemetry-enabled receiver.
  • Micro and nano drone projects needing full-range control in a minuscule footprint.
  • DIY multirotor builds utilizing FrSky XJT, X-Lite, or Taranis transmitters in D16 mode.
  • Redundancy-enabled aircraft setups for enhanced signal security in long-range or complex missions.

Frequently Asked Questions

What is the difference between SBUS and CPPM output on the R-XSR, and which should I use?

SBUS is a digital serial protocol offering all 16 channels with very low latency, and is the preferred choice for modern flight controllers like Betaflight. CPPM is an older analog pulse-train protocol limited to 8 channels and is typically used for legacy systems. For FPV drones, always use the SBUS output for best performance and channel count.

How do I enable the redundancy function on the FrSky R-XSR receiver?

The redundancy function requires the receiver to be flashed with FrSky's ACCESS firmware and registered to an ACCESS-capable transmitter (e.g., Tandem series). Once configured, you can connect a second receiver to the designated redundancy port, creating a dual-receiver setup for signal failover, enhancing reliability in challenging RF environments.

Can I use the R-XSR with a 1S LiPo battery directly?

Yes, the R-XSR's wide operating voltage range of 3.5V to 10V means it can be powered directly from a fully charged 1S LiPo (approx. 4.2V). Ensure your flight controller or wiring provides a clean 5V if using higher voltage battery packs to stay within the 10V maximum limit.
