Description

The EWRF ROTG01 receiver leverages a UVC (USB Video Class) protocol for plug-and-play compatibility with Android devices, eliminating the need for external power or complex drivers. Its compact PCB design houses a sensitive 5.8GHz RF front end capable of scanning 150 channels automatically, making it suitable for real-time video reception from analog VTXs across common FPV bands.

Engineered for both flight monitoring and diagnostic use, the module includes a graphical spectrum analyzer interface accessible via a companion app, allowing pilots to visualize signal strength, identify clean channels, and assess antenna performance. The unit operates on a standard 5V USB bus voltage and features reserved solder pads for AV and audio output, offering flexibility for integration into ground station setups.

Key Features

  • Universal Video Class (UVC) Driverless Operation: Recognized as a standard webcam by Android OS for zero-configuration setup.
  • Full 5.8GHz Band Coverage: Auto-scans 150 channels from 5645MHz to 5945MHz for comprehensive frequency agility.
  • Integrated Frequency Analyzer: Provides a real-time graphical display of RF spectrum for signal analysis and interference detection.
  • Low-Power USB Bus Powered: Draws only 200mA at 5V, making it suitable for extended use with mobile power banks.
  • Multi-Format Video Decoding: Supports both NTSC and PAL analog video standards for global compatibility.
  • Compact and Lightweight Design: Measures 61mm x 33mm x 9mm and weighs only 24g for highly portable field use.

Applications

  • Smartphone-based FPV monitoring for whoop, micro, and standard 5-inch racing drones.
  • Field-deployable spectrum analyzer for diagnosing VTX signal strength and identifying clean channels at crowded flying sites.
  • Lightweight backup or spectator display system, connecting directly to a phone or tablet.
  • Tool for benchmarking and comparing the performance of different 5.8GHz analog video transmitters and antennas.

Frequently Asked Questions

What Android versions and devices are compatible with this receiver?

The receiver requires an Android phone or tablet running version 6.0 or higher with hardware support for USB On-The-Go (OTG). Most modern Android devices meet this requirement. The module uses the standard UVC protocol, so no additional drivers are needed; it will be recognized as a standard USB video device.

How do I use the frequency analyzer feature?

The frequency analyzer graphical interface is typically accessed through a dedicated companion app provided by EWRF or a third-party UVC spectrum analyzer application. Once connected, the app will display a real-time graph of signal strength across the 5.8GHz band, allowing you to identify occupied channels, measure VTX output, and assess antenna performance.

Can this receiver power an external monitor or goggles?

The primary output is via USB to your Android device. However, the module includes reserved solder pads for composite AV and audio output. The included 'extra wire for external display' is provided for this purpose, allowing you to solder a connection to feed video to a secondary screen or recording device, though this requires manual modification.

What is the operational range and latency of this module?

Range is dependent on the transmitting VTX power and antenna setup. The receiver has a sensitivity of -90dBm, which is standard for analog modules. Video latency is approximately 100ms, which is typical for analog transmission and adequate for monitoring and analysis, though not ideal for low-latency acro flying through the phone's display.
