Mine just came yesterday. I can't believe how cool this is. I'll send a photo to my dad, an old, retired EE and college professor.</br>See you on AVRFreaks.</br>Torby

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

A product where the developer didn't spare the effort to maximize the feature set and quality. It's fantastic.

The only thing I'd like to see improved is the documentation. It would be nice if it were available in a downloadable, printable PDF file. The menus are certainly intuitive, but it would be a lot more useful if one could study the manual at leisure. Jim S.

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.)</br>Watch the video, order up one or two, and have fun. You won't regret having this little gem in your stable of toys.</br>W0CNN

I won this from 555 contest and It is really surprisingly small oscilloscope I've ever used. It has many good features like UART, I2C and SPI sniffing. Interesting logic analyzer :). Maybe one disadvantage is quite low bandwidth of oscilloscope, so you can only measure audio frequency band and I think that with increasing frequency error increases significantly, so do not expect any miracles. The same is true for spectrum analyzer. So in summary I think that it is nice toy for somebody, who is started in electronic worlds like as amateur. Because for playing with microcontrollers it has the best price/performance ratio. If you plan to build your own radio receiver this oscilloscope is not good choice. Because for its small bandwidth. But this price is very good for oscilloscope with these features :) So I am really very grateful for this award. And I only want to wish to creators: have bug free code :) and happy coding (designing)!

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

Great product !!!rnMake the next version with a bigger display and i'll be the first one to order

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

I just got my Xprotolab today, first off, shipping was very very fast, and unit itself is a little gem, this thing goes to my travel kit without any hesitation, it's not going to replace full size O-Scope, but it's not it's purpose, I tried to calibrate one of my company's VTR units, with Xprotolab, and managed to do so, couldn't get as good resolution as our tektronix but sure enough VTR read/record tracks are well within spec, this is all proof I need. Now, when does COMA comes out to public you said?

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/

Absolutely AWESOME product! Very professional implementation of a genuinely useful mixed signal o'scope. Well done firmware - NOT a demo - full function, extracts as much capability out of the hardware as possible. Permanent member of my tool box!!! Kit was easy to assemble, I used a coffee warmer hotplate and craft embossing (heat gun) with solder paste. Be careful with an iron, components are large, but tightly packed. Don't spend a lot of time on the OLED display connector, I pre-fluxed and pasted it, just "wiped" an iron set at ~300C over the pins to clean things up. (proper method is bar soldering). Display is a bit small for those of us over 50, but very readable, and once you understand the menu structure, you can setup a test quickly. I plugged an old cell phone charger into the micro-USB port, and now I have a portable, hand-held scope, stand-alone from the circuit under test. Thank you for all the hours invested in a high quality product!!!

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've had the XProtoLab now for several weeks now but I wanted to wait until I actually used it in a practical situation before I rated it. This weekend I was doing some experiments with my Arduino board. I had the arduino and XProtoLab on a large proto board running a stepper motor program. The XProtoLab was enormously useful for checking voltages and wave forms. This is what I call kitchen table electronics! This is a real tool!Butch Lacadie

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!

Maybe you should include a HUGE link to http://nfxdevelopment.wordpress.com/oscilloscope-pro/rnI'm in no way related to the mentioned site, but having a android front-end is a major double plus.

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.
