When you think about a piece of equipment like a mixed signal oscilloscope you usually think of, well, a piece of equipment. What you probably don't *imagine is a DIP package. The XMEGA Xprotolab is exactly that: The first ever mixed signal oscilloscope, logic analyzer and arbitrary waveform generator in a DIP module. At only 1 x 1.6 inches, this oscilloscope can be plugged *directly into a breadboard.
The on-board graphic OLED matrix can display waveforms, measurements and menu systems. You can also connect it to your PC and use Gabotronics' XScopes software to control the device and view waveforms.
The scope itself obviously allows simultaneous sampling of analog and digital signals but also has several advanced trigger modes, XY mode for plotting Lissajous patterns, phase differences or V/I curves, Spectrum Analyzer with different windowing options and even an arbitrary waveform generator with sweep on all parameters.
The awesome functionality-to-size ratio is due, in part, to the ATXMEGA32A4U microcontroller on board. We can hear you thinking, "This board has an ATXMEGA32A4U, an OLED display and USB interface? Scope or no scope, this would be a great development board!" Well Gabotronics had the same thought and installed a USB bootloader so there's no need for specialized programming tools!

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Noob - You don't need to reference a datasheet, but you will need to know basic power requirements.

It's an oscilloscope. It fits into your breadboard. Just take a moment to let that sink in... I bought this little thing for audio projects, and I am truly amazed at the features it has. Wave generator, oscilloscope, spectrum analysis, logic analysis, ... - you name it; it has it all. Even though the display might seem small, it makes up for that with the clarity it provides. One feature I'd like to see on this device in the future though is the ability to display a response curve. However it is possible to upload new firmware, so I'm pretty sure we'll be seeing this feature some time. Even if you don't need this - BUY IT!

This is the single best tool I've purchased for digital circuit development. It makes debugging I2C and SPI communications trivial, and has relieved head-scratch-itis on multiple occasions. I wouldn't want to do digital design without it.
Edit: Don't know why it says 4 stars, I wanted to give it 5 and can't seem to change it!
Edit again: ...and Sparkfun doesn't seem to understand how their website works, and can't change it for me. I apologize to Gabotronics -- this product really does deserve 5 stars!
