USB Logic Analyzer - 25MHz/8-Channel
Is your I2C bus not ACK'ing the way you expect? Do you need to discover a UART's mysterious baud rate? Or do you want to reverse engineer an SPI protocol? These all sound like jobs for a logic analyzer!
With the growing ubiquity of UART, I2C, and SPI sensors, logic analyzers are becoming a tool everyone needs in their toolbox. While the features of this LA don't quite measure up against those of, say, the Saleae Logic, it's still a great tool for quickly diagnosing most communication issues we encounter.
This is an 8-channel logic analyzer with support for sampling rates of up to 24MHz. It will work with both 3.3V and 5V systems (up to 5.25V max and 2.0V minimum on a high logic-level). The logic analyzer is powered via an included mini-B USB cable.
This logic analyzer works with sigrok -- an open-source, cross-platform signal analysis software suite. Check out our sigrok PulseView tutorial for help getting started.
The analyzer ships with Female-To-Female jumper wires. If you're using an Uno or board with female headers we recommend picking up a handful of Male-To-Male jumpers to connect the analyzer to the female headers.

made jumper cable
I made a jumper cable to go from the LA to the breadboard. Makes it easy to use with my Raspberry PI to check on serial signals
Great value!
I have the fully upgraded Saleae LA, but wow this LA is so much more compact and functional for the price. 25 MHz may not sound like a lot, but I think you may find, like me, that this covers most of your needs (i2c, spi, uart, etc).
Couldn't be happier
Works flawlessly and the PulseView tutorial got me up and running in no time.
Worth every penny and more
I'm a professional embedded developer, and I've used a lot of fancy logic analyzers, but I needed something cheap for home-use. I was completely blown away by this thing! After locating drivers and following installation/getting started material, the software PulseView worked on my Windows 10 machine without any problems.
Moreover, the software is intuitive, and has all the basic features you need. I was impressed by the wealth of signal parsing options in PulseView. You can name signals and save captures, and the software will remember your previous configuration on launch.
For $25, I can't think of a debugging tool of more value.
female to female jumpers make sense.... but then for header-based boards, wouldn't we need female to male jumpers, not male to male as listed? :-)
