Fantastic! I built this up to use in my Eurorack system, and it works great!

I have to admit, this device worth every penny!There are several "pcb like" oscilloscopes on the market, however I choose this because it have an x-y input.Screen is small but I can read it easily. I am almost 50 years old, I haven't my twenty's vision, however I'm not wearing yet eyeglasses either. In my condition I can read every character on screen.The most impressive is the huge number of functions in this tiny device!I place my own DIY pcb behind it, to turn it into a powerful fully parametrical component tester (Tracer). Since then I make amazing measurements which I couldn't done them before, and all in an absolutely portable way.For power supply I use a micro-usb phone charger or a $5 powerbank, which last for days or even weeks!Thanks again!Wish list:Hide usb and serial connector behind screen, to make device even smaller, at the same screen size.May add a backwards menu button.Faster Auto trigger if possiblePlotless trace at XY mode.

This product is worth every cent! The display is beautiful and the features are rich. It is perfect for audio applications. You will have a lot of fun with this little device. Guaranteed.

However, there are two problems I\'d like to point out:

Problem 1:
It is IMPOSSIBLE to install the drivers on Windows 8. Microsoft doesn\'t allow you to install this driver unless you have a valid certificate (which one has to buy for sixty dollars). This is not necessarily a problem of the device itself, but rather a problem created by Microsoft.

Problem 2:
When one uses the waveform generator, the amplitude changes when generating signals over 10kHz. This problem should be fixable to an extent by code though... :/

Best on site oscope to trouble shoot my installed arduino projects. I can carry this into my backyard or to a friends to work on projects. Most can\'t believe I am serious when I bring it out then marvel when I use it. One friend said it was cost effective to attach to a project and leave it. I love it so much I bought its parent the mini. Great job.

Great little device! Got my XProtoLab a week ago and the functionality really impressed me. The display-layout and menu structure is very well designed to give a convenient user-experience. Although there are only four buttons, I even did not need the user-manual to explore the core functions. For analyzing sub-MHz signals this device surely has the best price-performance-ratio you'll ever find!

I've read a lot of the hype about this product and it's all true. This was the best investment I've made. My expectations were far exceeded. Great job on this fine product. Thank you.

I bought two XProtolabs for use with synthesizers, and am very pleased. I snapped one into a mini-breadboard, plugged in a USB cable for power, and had waveforms from my TinySizer immediately. The refresh rate is very fast, more than adequate for audio work. http://www.flickr.com/photos/niobite/6917813225/lightbox/

Just got mine today. Awesome little device! The screen is really easy to read, since it has such high contrast. I highly recommend this!

What a cool scope. This thing now has a permanent home on my breadboard. But the world wants to know - can it run Doom?

incredible device, fantastic. Oled display is very small but good view quality

This is one of the FUNNEST ATXMEGA products out there to play with, and it's a great MSO/AWG/Logic Analyzer/Protocol sniffer to boot. Don't let the small display fool you- the OLED module has wonderful contrast and is perfectly readable, even given the extremely small fonts. The menu system is intuitive, the feature set is incredible, and the price is simply unbeatable. So far there has been a constant stream of updates to the firmware, so the product continues to improve. I have used the new I2C sniffer, and it comes in really handy when trying to debug protocol problems. I'm very impressed with the thought that went into the design, and Gabriel has managed to take full advantage of the ATXMega32 (and get around some of its known limitations). Another great fact- the power consumption of this beast is hardly anything- only 40ma. You can take full advantage of the full open source as well (but the MSO code is not included.)
Watch the video, order up one or two, and have fun. You won't regret having this little gem in your stable of toys.
