DSO Nano V2 - Pocket-Sized Digital Oscilloscope (Sale)

Replacement:TOL-11702. The V3 is available now and has a rugged metal enclosure! This page is for reference only.

This is a upgraded version of previous Nano, it is not a brand new model but there's still a lot of improvements.

DSO Nano v2 is a Digital Storage Oscilloscope designed for basic electronic engineering tasks. Within its smart shell, the device runs on ARM Cortex™-M3 32 bit platform, provides basic waveform monitoring with extensive functions. It is equipped with a 320x240 color LCD, microSD card storage, portable probes, LiPo battery, USB connection and signal generator. Due to palm size and handy performance, it fits in-field diagnosis, quick measurement, hobbyist projects and wherever convenience matters. Schematic and source files are also open for re-innovating.

A mini-USB cable is not included so you may need to buy one to charge your DSO. You can find mini-USB cables in the related items below. Also, you may need a 2GB Micro SD card to store wave signals.

Note: The "-" pole of the probe is directly connected to the GND of your PC when the device is connected via USB. Do not use the Nano for measurements while it's connected to your PC unless the target shares a common ground with your PC. Also, avoid touching the Nano when test leads are exposed to a high ground level offset and keep the Nano at a safe distance from other conductive material.

Features * Portable and lightweight * Color display * Waveform storage and playback * 6 triggering mode * 1Mhz Analog Bandwidth * Complete measurement markers and signal characteristic * Built-in Signal Generator * Accessories available * Open Source

  • Help how do I upload the BenF firmware???

    • Jeremy Sag / about 12 years ago / 2

      I have a post on the firmware including how to upgrade from the stock firmware here: http://thecustomgeek.com/2011/09/28/the-dso-nano-v2-pocket-oscilloscope-explained/ Hope this is a help. :)


      • Thanks! Everything went well, I got DfuSe installed in Ubuntu using WINE, etc. but then, when I open "DfuSe Demonstration" it just appears in the launcher and after a few "boot blinks" it just disappears from the launcher. What the...? Has anyone else done this in Ubuntu 11 and if so, do any of you guys have a solution?

        Anyone??? Stallman???

        • chaserrr / about 12 years ago / 2

          Check out the wiki. Apparently there's a ppa for dfu-util.


          • Thank you! Unfortunately my Ubuntu machine died on me rrrrrrr so I'll have to build from the source code on OS X. >:(

            • MikeGrusin / about 12 years ago / 8

              First world problems.

            • boj / about 12 years ago / 1

              If you do, can you please send it to me? I need an oscilloscope and this one looks nice, but I only have macs. And Ubuntu, but Wine broke.

      • free-bee / about 9 years ago / 1

        I'm stuck on step one. It sass to wait until it says "Please Connect to USB Host!" But mine says: "Please copy bin or hex file to the DFU virtual USB disk" even if it's not connected to the computer. And the dfuse software does not detect the scope. The scope has firmware 3.22

  • kwan3217 / about 13 years ago / 2

    This looks like one hackable piece of hardware. Nice fast processor, screen, plenty of buttons, lots of documentation, replaceable firmware. I have opened it up and found what looks like a serial port and maybe a bunch of other pins broken out. If you guys think hacking the Simon is cool, what do you think can be done with this? I'm noy going to hack it into a UAV controller, but I bet this could be done.

  • doceme / about 13 years ago / 2

    Great gift idea!<br />

  • adruniocaveman / about 11 years ago * / 1

    The one i received has a jst connector for the battery looks like they got tired of people complaining of shorted battery leads. Cool.. Also found a link for toughing up your nano v.2. http://www.danreetz.com/blog/2011/01/20/fix-your-dso-nano-2/. Did it works great. Moderator please add this link to the above list.

  • adruniocaveman / about 11 years ago / 1

    Excellent Product. Change to the Benf firmware and it golden! Get a 10x probe cut the plug off and add a phono plug and it's complete.

  • noggy / about 11 years ago / 1

    Hi, does it come with the probes?

    • adruniocaveman / about 11 years ago / 1

      Yes it does. a set of microclips and a set of pointy ones.. Then I hacked a 10x 1x switchable oscilliscope probe for it too.. works excellent.

  • noggy / about 11 years ago / 1

    does it come with the probes?

  • This scope is awesome!

  • ChadWV / about 12 years ago / 1

    Just ordered mine, never used one before, any tips on getting to know how to use one of these. I love electronics and plan on building lots of stuff.

  • They're serious when they say don't have it plugged in while making measurements. Blew mine up D: oops. Definitely worth having around though, I miss the little guy.

  • Member #270309 / about 12 years ago / 1

    I just ordered one and it didn't come with a usb cord to charge it. That's nice. I'm assuming they are not supposed to come with it?

  • Thimplum / about 12 years ago / 1

    Hey... Who cares about the oscilloscope... THAT IS ONE NICE LCD! Seriously, you guts should sell it separately.

  • Member #297702 / about 12 years ago / 1

    Very poor quality

  • Microman / about 12 years ago / 1

    I bet the moment I buy one, the newer, cheaper model will come out.

  • ricvan / about 12 years ago / 1


  • Me want me want!

  • Dang, I can't afford it. Hmm, although I didn't take into account the $70 in house-sitting money I just got...

  • aos00 / about 12 years ago / 1

    The probe is included? What items are included?

    • SomeGuy123 / about 12 years ago / 1

      It includes two types of probes, a stand, and a nice case (shown in picture).

  • ddd999 / about 13 years ago / 1

    The product description and the manual both claim this device has 1MHz analog bandwidth at a sample rate of 1MS/s.
    Somebody call the Nobel prize committee, Seeed has broken the Nyquist limit!
    1MSPS is pretty good for this little thing, but calling its bandwidth 1MHz is just plain incorrect. I wouldn't trust it much beyond 100kHz or so.

    • Segphalt / about 12 years ago * / 1

      It isn't seeed to blame, if you look at the seeed site, they mark it as 200khz analog bandwidth. (the product doc is old.) The amusing part is the o-scope kit from JYE some how costs far less and claims a 1Mhz (I have it 500khz is the only thing I would consider acceptable) analog bandwidth, proof in the pudding in the just because it looks better doesn't mean it works better. The DSO has more functions though.
      If you want an O-scope, go the ebay route, its a better value/cost ratio 9 out of 10 times.

  • Mark D. / about 13 years ago / 1

    How many channels, one or two?

    • SomeGuy123 / about 12 years ago / 1

      It has one channel. The other jack is for the signal generator.

  • Member #11099 / about 13 years ago / 1

    I'm reasonably happy with the performance of this little scope. But recently discovered there's no low-voltage protection for the LiPo battery, which results in being able to totally deplete it. This is very bad, as LiPo technology does very poorly with this kind of abuse. At best it shortens the life of the battery significantly.
    So, folks, make sure you turn this baby off when not in use. Don't let it go dark on its own.
    I hope they fix this problem in a future release. I'll probably end up transplanting the circuit from a cell phone battery. It looks like there's room for taping a thin card next to the battery.
    Sounds like a good Sparkfun product (LiPo under-voltage protection circuit). Hint, hint.

    • MoriFi / about 13 years ago / 1

      if you put a sparkfun lipo in it, they have built in under voltage protection.

  • Bunk / about 13 years ago / 1

    what are the rubber pads for? there is a wide one and a thin one.
    is it for the stand?

    • SomeGuy123 / about 12 years ago / 1

      Yes, they go on the inside of the stand to avoid scratches to the osc.

  • ThePolarCat / about 13 years ago / 1

    How to charge this thing? Through the micro USB port or does it come with a charger?

    • SomeGuy123 / about 12 years ago / 1

      It is charged via usb. You could also open it up with the included screwdriver and remove the battery to charge it.

      • I lost 2 of the 4 screws last night (edit: I found one :D) :( I need one of those clear boxes where you reach your arms in to do stuff with tiny screws.

  • ElectronicsNerd / about 13 years ago / 1

    Pretty responsive little scope, perfect for a lot of basic stuff. The BenF firmware is a must; the end result is a pocket-sized product that acts like an expensive bench scope. Measurements in the new firmware appear in a list, just like my HP. It's easy to take this anywhere and have answers fast.

  • lcox / about 13 years ago / 1

    Didn't see it covered in the feature set - Is it possible to store a screen shot of a waveform on the SD card? Is there any method, SD-card or other, to export a screen shot?

    • barnaclebeau / about 13 years ago / 1

      Yes. You can save .BMPs to the card, and export events in .xml... at least with the benf firmware. I never bothered to get familiar with the official firmware.

    • cjenkins / about 13 years ago / 1

      Hi, if you find out how to do it please share it with us.

  • GooseSG / about 13 years ago / 1

    Any ideas when these will be back in stock? I have some FreeDay cash to spend!

  • Colecago / about 13 years ago / 1

    If you are on the fence, I'd wait for this

  • Member #38151 / about 13 years ago / 1

    It's nice.

  • mike50 / about 13 years ago / 1

    This is an awesome product, but is even better with the BenF 3.33 firmware upgrade. This changes the menu system so it is much simpler to use and changes the SD card support so that it is FAR better.
    See http://dso.seeedstudio.com/viewforum.php?f=12&sid=c56b6dda0105d138bdb326a5c1e82cb7

  • mvsopen / about 13 years ago / 1

    The original model of this OScope had a totally wrong charger for the supplied LiPo battery type (+5 volts, a small resistor, and nothing else). Do you know if that has been corrected with this version?

    • mike50 / about 13 years ago / 1

      The V2 DSO Nano uses an LTC4054 Li-Ion Charger to manage the LiPo.

  • Dougie / about 12 years ago * / 0

    I'm trying to update a new, out of the box Nano V2 to Benf 3.62, drivers installed well with dfuse 3.0.1 on windows 7 64 bit. the upload of app 3.62 and lib 3.52 seem to go fine, but when I turn off and back on, I still see the Seeedstudio firmware prompt. Am I missing a step? The nano display always reads "firmware upgrading… Please Wait" – forever – should I keep waiting? or just off/on?
    Any suggestions??

    • I get this also... I can't figure out why it's happening...
      Can someone help?

      • Member #83180 / about 12 years ago / 1

        Anyone ever get this figured out. I too am trying to update new Nano V2 to Benf 3.62 on Win 7 64 bit. I cannot even get Win 7 to load the driver to see the device in DfuSe Demo V3.0.

        • chaserrr / about 12 years ago / 1

          Couldn't for the life of me get it to work on 7 64-bit. Booted into Ubuntu and followed http://seeedstudio.com/wiki/Dfu-util

          You could probably do it from a liveCD.

          • tommytwoeyes / about 12 years ago / 1

            Worked perfectly for me the first time using dfu-util v5 on Ubuntu, also.

            In Windows Vista, fail.

            • foundrysmith / about 12 years ago / 1

              Failed for me also in Vista. Oddly enough, I was able to successfully upload BenF in XP!

              • adruniocaveman / about 11 years ago / 1

                DfuSe Demo V.3.0.1 will not work in windows 7. had to use virtualbox with windows xp and DfuSe v. 3.0. Worked perfectly..

                • adruniocaveman / about 11 years ago / 1

                  also you must use a sd formatter program with the card in the unit and plugged in to the pc if you are having problems with sd errors. worked for me
