sku: TOL-10244
Description: 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.
- 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???
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???
Check out the wiki. Apparently there’s a ppa for dfu-util.

Great gift idea!
Here is a link to the page that has the source code:
http://code.google.com/p/dsonano
This is a direct link to the schematic:

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.
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?
The V2 DSO Nano uses an LTC4054 Li-Ion Charger to manage the LiPo.
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
It’s nice.
If you are on the fence, I’d wait for this

Any ideas when these will be back in stock? I have some FreeDay cash to spend!
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?
Hi, if you find out how to do it please share it with us.
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.
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.
How to charge this thing? Through the micro USB port or does it come with a charger?
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.
what are the rubber pads for? there is a wide one and a thin one.
is it for the stand?
Yes, they go on the inside of the stand to avoid scratches to the osc.
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.
if you put a sparkfun lipo in it, they have built in under voltage protection.
How many channels, one or two?
It has one channel. The other jack is for the signal generator.
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.
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.
The probe is included? What items are included?
It includes two types of probes, a stand, and a nice case (shown in picture).
Dang, I can’t afford it. Hmm, although I didn’t take into account the $70 in house-sitting money I just got…
Yay! I’m getting one with my next order!
Me want me want!
Kooil
I bet the moment I buy one, the newer, cheaper model will come out.
Very poor quality
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?
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.
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.
