iFlight ExpressLRS ELRS Nano Receiver – 2.4GHz 70mm Mini Antenna

The iFlight 2.4GHz ELRS Nano Receiver brings the high refresh rates, low latency, and exceptional range of the open-source ExpressLRS project to a microscopic footprint. Designed for FPV pilots building micro drones, whoops, and space-constrained freestyle rigs, this receiver ensures a reliable radio link without sacrificing critical stack space. It comes paired with a 70mm mini antenna, providing just enough coaxial length to clear carbon fibre frames and batteries for optimal signal reception without adding unnecessary wire bulk.

Key features

• Ultra-compact Nano form factor designed for high-density micro and freestyle builds.
• Powered by the industry-standard ESP8285 MCU and SX1280 RF chip for proven ExpressLRS performance.
• Includes a 70mm mini antenna to balance convenient mounting with clear signal routing.
• Supports high packet rates for significantly reduced control latency.
