Radiomaster XR1 Nano Multi-Frequency ExpressLRS Receiver – 2400 – The Ultimate Compact Link

Unlock unprecedented range and reliability for your FPV drone with the Radiomaster XR1 Nano Multi-Frequency ExpressLRS Receiver. This ultra-compact ExpressLRS receiver leverages the advanced Semtech LR1121 transceiver to deliver rock-solid 2.4GHz control with exceptional penetration and resistance to interference. Whether you’re engaged in long-range exploration, competitive racing, or freestyle flying, the XR1 provides the robust, low-latency link you need to fly with absolute confidence. At just 20 x 13mm and 1g, it’s the perfect upgrade for any build where space and weight are at a premium.

Core Technology & Performance:

• Semtech LR1121 Transceiver: The heart of the system, providing excellent sensitivity and range on the 2.4GHz band, outperforming many traditional receivers.

• ExpressLRS Protocol: Enjoy the benefits of the open-source ExpressLRS ecosystem—extremely low latency (up to 1000Hz packet rates), high refresh rates, and robust frequency hopping for a glitch-free connection.

• High-Power Telemetry: 100mW telemetry output ensures strong signal return to your transmitter, providing vital flight data like RSSI and link quality.

• Multi-Frequency Ready: While this model is optimized for 2.4GHz, the platform’s design allows for flexibility. For pilots needing ultimate penetration, our Sub-G 900MHz ExpressLRS receivers are also available.

Key Features for Pilots:
