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, Stratux, Planeplotter for Windows, Mac, Linux, Android & Raspberry Pi.

Mighty MiteReview by spRocket
A pair of these and RATLsnakes to go with them replaced a frustrating pair of no-name SDRs that I had been trying to use on a Raspberry Pi 3B+. The difference was immediately evident, with spot-on tuning and absolutely no drift. Since I'm mostly hunting UHF narrowband FM, accurate tuning is a must, and I was amazed when I was able to turn the PPM to zero. I'd say the performance is comparable to a couple of SMArt v4s I've run 24x7 for several years, which is to say superb.

Yes, they do get quite hot, even with the heat sinks attached. I was expecting it, and it's clearly not a problem after an all-day session. With a GPS hat, some heavy underclocking/no undervolting, and unnecessary LEDs turned off (I need Bluetooth and Wi-Fi), I can get about 13½ hours off a stout power bank.

If the heat is not a problem for you, they pack a lot of punch in a tiny package. (Posted on 1/15/2023)

Performance OK, but dimensions do not match spec. Should read 25 x 17 x 8 mm excluding USB connector (Posted on 6/24/2019)
