Pros- price, size(it's freakishly small for what it does), tons of features, totally open source with 3rd party firmwares available and an active online community
Cons- one channel, frequency and bandwidth are too low for RF work, Stock firmware is HORRIBLE so flashing it is pretty much mandatory.

Bottom line- This device is an open source handheld oscilloscope based on a 32 bit processor designed for MP3 players. It even looks like an mp3 player. (The newer models do not.)

Though the form factor is different, it is functionally identical to the DSO Nano V2 which costs $20 more. If you want a super affordable oscilloscope for hobby/automotive or audio frequency use, this might be for you, with one caveat- REPLACE THE FIRMWARE!!! The stock firmware is so bad it renders the device useless. Not only are the menus a mess, but the trigger/sampling algorithm is broken so triggers are sometimes missed. If you expect this device to perform well out of the box, you'll be disappointed.

Luckily this device is OPEN SOURCE! Even more lucky is that there is a firmware that resolves pretty much all the software issues. (It's called 'BenF'). Even though it wasn't developed by the manufacturer, it is the de facto 'firmware in use'. Once I flashed it was easy to see why. The Nano went from incomprehensible to easy in 5 minutes. Honestly I'd give this product 5 stars if it shipped with the 'BenF' firmware installed.

As for the capabilities, it's quite the little device. It samples at 1MHz. which means it's useful to about 200kHZ for analog signals, higher of course for digital signals...

DSO 201 Nano V1
Device Firmware 3.26A

In a nutshell this is a dream for the DYI Audio hobbyist!
ONCE YOU'VE CHANGED THE FIRMWARE TO BENF

Yes the scope is only reliable up to 100 Khz but for testing/repairing or modding Hi-Fi, it is the best thing since sliced bread.
I'm not going trough all the things that the scope can do as this has been discussed in great detail by other users.
One thing I would like to mention:
As the scope is not connected to mains, you can safely measure across components (as long as the scope is NOT plugged in via a USB cable !!!!)
The scope has only DC coupling (not a real handicap)
IF you want AC coupling, you can solder a 0.1uF 600V (non polarized) polyester film capacitor in series with the probe (can put a switch to bypass cap)
IF you want to use regular scope probes, you can by an MCX male to BNC female pigtail for $5

My unit came loaded with Paul's firmware.
The firmware is clumsy, unpredictable and refused to see the 2G Sandisc Micro SD

According to some online info, you should download a utility called DfuSe and upload
BenF's incredible firmware.
You can then upload BenF's app.dfu and lib.dfu
The DfuSe refused to recognize my scope!

OK don't panic, Firmware 3.26A and above no longer uses dfu files and actually the firmware upgrade process is EASY.

I downloaded the latest original manufacturers firmware:
201AP263.hex and LIB_A227.hex
Put those 2 files on your desktop
Connect the scope to your PC and hold the DOWN-button while switching the power to on.
Note: you do NOT need an SD card in the scope to do this upgrade!

Only had the device a couple days, but is definitely taking waveforms. Bandwidth is limited to 1MHz, so you won't be taking any high speed signals. But for simple, quick measurements, it seems like it's doing well.

Upgrading firmware took a while to figure out. The latest DSO Nano's are shipping with a new bootloader, that requires a different firmware upgrade methodology. The manual shipped with the product is wrong. If your Nano has "Device Firmware Upgrade" newer than V2.6 (mine is V3.22A), then you should follow the procedure below:
- Hold the "-" button down, while you power on the device (NOTE: this is diff't from the manual)
- The screen should come up with Serial number, Licence (sic), and "Device Firmware Upgrade Vx.xx"
- Plug the USB into your PC, you should see a new disk show up in your file explorer
- Download latest *HEX* files, not DFU files (NOTE: this is diff't from the manual). All the forum-o-sphere seems to like BenF
- For BenF, there will be two hex files (APP and LIB). For other upgrades, there is often only one hex file.
- Copy the hex files from your download to the Nano disk *one at a time*. This is really important. The Nano can only handle one file at a time (I spent about an hour of frustration figuring this out).
- For each hex file copied, wait until the Nano "accepts" the file before powering off or copying another file. You will know it is accepted b/c the Nano disk will get dropped by the PC, then reloaded and the extension of the file you copied will now be .rdy (instead of .hex). If you have a .err extension, then something went wrong.
- Once all files are copied, then simply power cycle the Nano (don't hold any buttons down).
