Description

The RadioMaster RP4TD ExpressLRS 2.4GHz Diversity Receiver is engineered for pilots demanding the highest reliability and performance in FPV and fixed-wing applications. Its true diversity architecture, utilizing dual independent SX1281 RF chips and dual temperature-compensated crystal oscillators (TCXOs), ensures exceptional signal-to-noise ratio (SNR) and resistance to multipath interference, even in challenging RF environments.

Built around an ESP32 MCU, the receiver integrates a dedicated WiFi module for seamless, cable-free access to the ExpressLRS WebUI. This allows for real-time configuration, packet rate adjustments, and firmware updates without physical disassembly. The optimized PCB layout and DCDC power regulator contribute to efficient heat dissipation and stable operation across its full 4.5-12V input range, supporting integration into both lightweight drones and larger models.

Key Features

  • Dual-Channel True Diversity: Two independent SX1281 radios and TCXOs provide superior signal reception, switching between antennas to maintain the strongest link.
  • High-Power Telemetry: Capable of dual 100mW RF telemetry output for robust, long-range bidirectional communication with the transmitter.
  • Wireless Configuration via WiFi: Built-in ESP32 WiFi enables direct connection to the ExpressLRS WebUI for firmware updates and parameter tuning without a USB cable.
  • Advanced Thermal & Power Management: A reliable DCDC power supply circuit ensures cool operation and stable voltage delivery, enhancing longevity during extended flights.
  • Gemini Mode Compatible: Supports advanced ExpressLRS features for enhanced connectivity options and network performance.
  • Optimized Antenna Design: Includes two upgraded, durable 65mm 2.4GHz T antennas for improved signal pattern and mechanical resilience.
  • Extended Interface Options: Provides UART pads for connecting additional peripherals or telemetry sensors beyond the primary CRSF connection.
  • Pre-Configured Performance: Ships with ExpressLRS V3.3.0 firmware pre-installed, ready for immediate binding and flight.

Applications

  • High-performance 5-inch and 7-inch FPV racing drones requiring ultra-low latency and reliable long-range control links.
  • Long-range fixed-wing and wing platforms where signal diversity is critical for maintaining link integrity over distance.
  • Heavy-lift cinematography drones that benefit from the robust telemetry and stable 4.5-12V power input range.
  • Compact whoop and micro drone builds where the small footprint and integrated WiFi simplify setup and configuration.
  • DIY robotics and autonomous vehicle projects utilizing the CRSF protocol and UART interfaces for custom control integration.

Frequently Asked Questions

What is the advantage of the dual TCXO design in the RP4TD receiver?

The dual Temperature Compensated Crystal Oscillators (TCXOs) provide exceptional frequency stability by actively compensating for temperature fluctuations. This minimizes frequency drift, ensuring consistent and reliable signal reception even in extreme environmental conditions, which is critical for maintaining a solid control link in long-range or high-interference FPV scenarios.

How do I update the firmware or configure the RP4TD receiver?

The RP4TD features a built-in ESP32 WiFi module. Power the receiver, connect to its WiFi network from a PC or smartphone, and access the ExpressLRS WebUI via a browser. This interface allows for wireless firmware updates, packet rate configuration, binding management, and parameter adjustments without needing a physical USB connection.

What voltage range does the RP4TD receiver support, and how is it powered?

The receiver operates on a wide DC input range of 4.5V to 12.0V. It is typically powered via the 5V or BEC output from your flight controller through its CRSF wire. Its integrated DCDC power supply circuit ensures efficient voltage regulation and reduced heat generation across this entire range.

Is the RadioMaster RP4TD compatible with my existing 2.4GHz ExpressLRS transmitter?

Yes, the RP4TD is fully compatible with all 2.4GHz ExpressLRS transmitters, including external modules and radios with built-in ExpressLRS. It uses the standard ExpressLRS V3.3.0+ protocol, ensuring seamless binding and operation with your existing RadioMaster, HappyModel, or other ELRS-compatible radio gear.
