## Overview

The NooElec NESDR Nano 3 is a premium, ultra-compact RTL-SDR dongle featuring a robust aluminum enclosure with EMI shielding, an industry-best 0.5PPM temperature-controlled crystal oscillator for minimal frequency drift, and a versatile articulating SMA connector compatible with SMA and MCX antennas. Designed for seamless integration in tight USB spaces like Raspberry Pi setups, it includes a custom heatsink for enhanced thermal management and comes with a 2-year warranty, making it a top choice for professionals and enthusiasts seeking reliable, portable software-defined radio performance.

## Description

Say goodbye to blocked USB ports! The tiny NESDR Nano 3 is the ideal SDR for portable and embedded applications. Quad SDRs on a Raspberry Pi? USB OTG? Not a problem for the NESDR Nano 3! The Nano 3 is just 17mm x 8mm x 20mm weighs only 15g!The Nano 3 is built into a high-quality brushed aluminum enclosure. In conjunction with the 2 internal silicone heat pads, this ensures that heat is removed from board-level and to the exterior where it belongs. The aluminum enclosure ensures that EMI is kept out out of the sensitive SDR circuitry, and emissions from the digital circuitry are contained within the SDR enclosure. The latter is especially important in EMI sensitive environments like automotive and flight applications!An articulating, right-angle female SMA connector is included to allow you to attach both male SMA and male MCX antennas directly to your SDR. The NESDR Nano 3 contains the same custom TCXO we include in our NESDR SMArt series. This 0.5PPM, ultra-low phase-noise TCXO is by far the highest performance TCXO available in ANY low-cost SDR. We are so confident of the reliability and stability of this SDR that we offer a full 2-year warranty--the longest in the industry. CAUTION: The enclosure will get hot! This is by design, and will not affect performance of the SDR. Please be cautious when touching the SDR after prolonged usage! A custom heatsink, which can optionally be affixed to either side of the SDR to further improve heat dissipation, is included with your purchase. This RTL-SDR is based on the R820T2 tuner IC made by Rafael Micro, which means an approximate tuning range of 25MHz-1700MHz . There is also an RTL2832U IC on board to provide basic demodulation and USB interface functionality. Full compatibility with a wide variety of popular SDR software packages, such as Matlab, CubicSDR, HDSDR, SDR Touch, Planeplotter for Windows, Mac, Linux, Android & Raspberry Pi.

Review: Great design, no wasted space. Does get pretty hot - I am impressed by the tiny size and performance of this. I like the fact they designed it with the raspberry pi usb port dimensions in mind such that they fit perfectly even with 4 installed (not sure if this would be possible due to power requirements however) i know 2 is possible though. The heat sink shows that you get 2, which would have been nice because these puppies get HOT when in use. I came up with a way to drain even more heat though by using a solid aluminum case by FLIRC and slipping a piece of thermal pad/tape in between the FLIRC case and the radio's aluminum case where they meet. It's designed with very close tolerances so this works very well almost meant to be! you get a little bit more heat dissipation that way. Just search for FLIRC raspberry pi case on desertcart and you'll find it. Anyway, this is Nooelecs best sdr design so far, imho. Some people did mention that the screws holding on the case can become stripped and loose easily, i haven't experienced this but it makes sense considering how little surface area there was for cutting threads and how soft aluminum is, so be careful with that or add a drop or two of thread locker, or super glue if you want and it should be alright. Mcx to sma adapter included, the mcx to type N I have snapped in though fits snugly and there is no wiggle. This is reassuring compared to some previous models that were sometimes loose.
Review: Tune in Tokyo - I can listen to the radio, it’s really capable and amazing. ATC, FM, AM the spectrum is your playground.

## Questions & Answers

**Q: Where can I get the enclosure?**
A: Hi!  The SDR is installed in the enclosure, it is not required to purchase it separately.  

Perhaps you meant you want to purchase for a different version of the NESDR Nano?  If that's the case (ha!), sorry, but the PCB was completely redesigned and is a different size.  The enclosure will not fit other SDR models.

**Q: Will this work with OTG?**
A: Works on OnePlus 7T (type-c usb3.1) with i-teknik USB-C hub. Did not work with a cheaper USB-C to usb-a OTG adapter. This also did not work in my OnePlus with type-c USB2.0 port with either hub or adapter.

**Q: Can I buy just the Aluminum Enclosure and heatsinks?**
A: No, they are not available for sale separately, sorry.  They are designed specifically for the Nano 3 circuit board, which is a much smaller size than our previous models.  Thank you

**Q: Will this work with radioconda and/or sdr angel?**
A: Yes, thanks!

### ⭐⭐⭐⭐⭐ Tune in Tokyo
*by B***N on August 19, 2025*

I can listen to the radio, it’s really capable and amazing. ATC, FM, AM the spectrum is your playground.

### ⭐⭐⭐ Works, runs hot, case rattles.
*by T***R on March 7, 2018*

Works as expected but it gets very hot and only comes with 1 heat sink as opposed to the 2 that are in the picture so I'm only giving it 3 stars. Otherwise it would get 4 because the aluminum casing isn't sized correctly. The end pieces are made a little too big and rattle even with the screws tightened.
