Description

The RadioMaster RP2 V2 Nano receiver represents a significant evolution in miniaturized radio control, integrating the full ExpressLRS 2.4GHz protocol into a package smaller than a fingernail. Its design centers on the ESP8285 microcontroller and the Semtech SX1281 RF chip, which together deliver the low-latency, high-packet-rate performance critical for competitive FPV racing and long-range exploration.

Engineered for reliability, the receiver incorporates a Temperature-Compensated Crystal Oscillator (TCXO) to maintain frequency stability across a wide range of operating temperatures, ensuring consistent link integrity in demanding environments. The elimination of an external UFL connector via the integrated ceramic antenna not only reduces weight and size but also removes a common point of mechanical failure, making the RP2 V2 exceptionally durable for its class.

Key Features

  • TCXO-Enhanced RF Stability: Temperature-compensated crystal oscillator ensures precise frequency control for reliable signal reception in varying thermal conditions.
  • Optimized Thermal Management: Improved PCB layout and design promote superior heat dissipation from the SX1281 RF chip during sustained high-refresh-rate operation.
  • User-Friendly Solder Pads: Redesigned, enlarged solder pads simplify wiring connections for the 5V, Ground, TX, and RX pins.
  • Integrated Status LED: Top-mounted LED provides clear visual feedback for binding status, signal strength, and operational mode.
  • ExpressLRS v2.4 Firmware Pre-Installed: Ready for use out of the box with support for Dynamic Power, Model Match, and Telemetry.
  • High-Speed Serial Protocol: Supports refresh rates from 25Hz up to 500Hz (Full Res) or 1000Hz (Diversity), configurable via the WebUI.
  • Wide Voltage Compatibility: Operates on a standard 5V supply from a flight controller BEC or regulated power source.

Applications

  • Ultra-Light FPV Racing Drones: The nano size and sub-1g weight make it perfect for 2.5-inch and 3-inch toothpick-class racers where every gram counts.
  • Micro and Whoop Drones: Ideal for installation in cramped frames like BetaFPV Meteor and HappyModel Mobula series, providing full ExpressLRS performance.
  • Long-Range Mini Quads: Enables extended-range flying on sub-250g lightweight builds where space is limited but reliable control is essential.
  • Fixed-Wing and Wing Platforms: Suitable for small wings and gliders requiring a compact, lightweight receiver with telemetry capabilities.
  • DIY Robotics and Rover Projects: Provides a high-performance control link for small-scale robotic platforms using CRSF serial communication.

Frequently Asked Questions

What is the operating voltage range for the RadioMaster RP2 V2 receiver?

The RP2 V2 receiver is designed to operate on a standard 5V supply. This voltage is typically provided by the 5V BEC (Battery Eliminator Circuit) output on most modern flight controllers. It is crucial not to exceed this voltage to prevent damage to the onboard ESP8285 MCU and RF components.

How do I update the firmware or configure the RP2 V2 receiver?

The receiver features a built-in WiFi access point powered by its ESP8285 MCU. To configure it, power the receiver and connect to its WiFi network from a PC or smartphone. Then, open a web browser to access the WebUI, where you can adjust settings like binding phrase, model match, packet rate, and update to the latest ExpressLRS firmware directly.

Can I use this receiver with a 900MHz ExpressLRS transmitter module?

No, the RP2 V2 is strictly a 2.4GHz receiver and is only compatible with 2.4GHz ExpressLRS transmitters, whether they are external modules (like the RadioMaster TX series) or built-in 2.4GHz ELRS systems in radios like the RadioMaster Boxer or Zorro. It uses the 2.4GHz ISM band from 2.404 to 2.479 GHz.

What is the advantage of the integrated ceramic antenna versus a UFL connector?

The integrated ceramic SMT antenna eliminates the need for a separate antenna wire and UFL connector, reducing total weight (to just 0.55g) and minimizing physical size. This makes the receiver more durable by removing a common point of mechanical failure (a loose UFL connector) and is ideal for ultra-compact builds where an external antenna would be impractical or add drag.
