Overview
The Nooelec NESDR Nano 3 is an ultra-compact software-defined radio (SDR) receiver based on the RTL2832U and R820T2 chipsets. It covers a wide frequency range from 25MHz to 1700MHz and features a high-precision 0.5PPM TCXO to minimize frequency drift. The aluminum enclosure provides excellent EMI shielding and heat dissipation, all in a tiny 17×8×20mm, 15g package. With USB connectivity, it works seamlessly with PCs and Raspberry Pi, making it ideal for ADS-B, FM radio, amateur radio, and more. An optional custom heatsink can be attached to both sides for improved thermal performance.
Connectivity & Compatibility
The NESDR Nano 3 connects via USB 2.0. It comes with a breakaway SMA connector that allows direct attachment of both male SMA and male MCX antennas. It supports Windows, macOS, Linux, Android, and Raspberry Pi OS, and works with popular SDR software such as CubicSDR, HDSDR, SDR Touch, Stratux, Planeplotter, GQRX, and SDR#. Any platform with librtlsdr support can use it. It also integrates with advanced tools like MATLAB and GNU Radio for signal processing.
Product Info
The Nooelec NESDR Nano 3 is available on online retailers for approximately ¥9,495. It comes with a 2-year warranty and includes a custom heatsink and an SMA-to-MCX adapter. Market positioning is entry to mid-range SDR, with a focus on portability and precision. Compared to other RTL-SDR dongles in its price range, it offers superior TCXO accuracy (0.5PPM) and aluminum shielding. It is assembled in North America, ensuring quality control.
Best Use Cases
- Aviation enthusiasts: Ideal for receiving ADS-B signals at 1090MHz to feed FlightRadar24 or ADSBexchange. Its small size makes it unobtrusive when plugged into a laptop or Raspberry Pi. For long-range reception, an external LNA or high-gain antenna is recommended. Pairing with a GPS-equipped Raspberry Pi can provide more accurate position data.
- SDR beginners: An affordable entry point with solid performance. Works immediately with free software like CubicSDR. Experiment with FM radio, airband, and weather satellite images. However, if you need to receive above 1700MHz (e.g., 2.4GHz Wi-Fi or cellular), consider a higher-frequency SDR like the RTL-SDR Blog V4 or Airspy.
- Raspberry Pi projects: Ultra-compact and low power, ideal for headless Pi setups. Works great with Stratux or dump1090 for ADS-B. Combine with GPIO pins for custom projects. Note that limited USB ports may require a hub, and stable power supply is critical for SDR performance.
- Mobile/field use: Lightweight and rugged aluminum build makes it suitable for portable operations or drone payloads. Be aware that the enclosure can get hot during extended use, so handle with care. For outdoor use, consider a waterproof enclosure.
