RadioMaster XR3 Nano – Multi-Frequency ExpressLRS Receiver with Antenna Diversity

Ultra-lightweight ELRS receiver with dual antennas, multi-band support, and Wi-Fi WebUI

The RadioMaster XR3 Nano is a compact and versatile ExpressLRS receiver featuring true antenna diversity for optimal signal stability. It is available in three distinct variants:

  • 2 × Dual-Band (2.4GHz + 900MHz): Automatically selects the best signal across both frequency bands without antenna swapping.
  • 2 × 2.4GHz: Optimized exclusively for 2.4GHz ELRS systems – perfect for racers and freestylers.
  • 2 × Sub-G 900MHz: Built for long-range FPV setups operating in the Sub-G 868/915MHz band.

With onboard Wi-Fi and WebUI interface, firmware updates and configuration are quick and easy – no cables needed.

Key Features
