STARDRONE RP1 Nano Receiver | 2.4GHz ELRS ExpressLRS for FPV Drones

Introducing the STARDRONE RP1 Nano Receiver

Meet a compact ELRS 2.4GHz receiver designed for FPV pilots who want reliable connections in tight builds. The RP1 blends open‑source flexibility with practical performance, pairing an ESP8285 MCU with an SX1280 RF chip to deliver clear, responsive link management without adding bulk to your frame.

Core tech that powers dependable ELRS links

Open‑source design gives you visibility into the firmware ecosystem, while the onboard ESP8285 MCU handles control logic efficiently. The SX1280 RF transceiver supports robust communication across typical 2.4GHz ELRS configurations, helping your FPV system stay responsive under dynamic flight conditions.

• Open‑source RP1 Nano receiver designed for ExpressLRS ecosystems, compatible with most ELRS modules and remotes.
• Low‑latency, high‑refresh‑rate RF performance tailored for FPV drones, Tiny Whoops, and small RC planes.
• 65mm UFL antenna socket for flexible full‑range antennas and a rugged, longer‑reach setup when needed.
• Heat‑dissipating PCB design improves thermal management during extended sessions.
• Built‑in TCXO oscillator for stable frequency control across temperature variations.
• Ultra‑lightweight nano form factor at roughly 2.2g, including the antenna.

Real‑world use cases and how it helps your builds

Whether you're racing an FPV drone, cruising a micro build, or piloting a fixed‑wing RC plane, RP1 offers a compact footprint with consistent performance. The 65mm antenna and UFL socket provide flexibility to optimize range and durability for field deployments.

• Low‑latency, reliable control and smoother response during rapid moves and aerial tricks.
• Feasible integration into small frames without adding bulk, preserving agility and weight balance.
• Stable operation in varying temperatures, supporting flights in different climates or seasons.
• Compatibility with a wide array of ELRS modules and remotes, reducing setup friction when swapping gear.

What’s in the box and how it fits your build

The package keeps things straightforward for quick installations—RP1 nano receiver, 65mm UFL antenna, user manual, and a CRSF wiring lead. Together, they support easy mounting inside confidence‑boosting spaces on micro airframes.

Key specs at a glance

Weight, footprint, and antenna options matter in FPV setups, and RP1 is designed with that in mind. The 2.2g total weight, UFL socket, and compact PCB layout help preserve flight characteristics while enabling robust ELRS integration.
