1Set USB Logic Analyzer Device Set USB Cable 24MHz 8CH 24MHz 8 Channel UART IIC SPI Debug for Arduino ARM FPGA M100 Hot

Very handy as a quick and highly portable analyzer for field work. Well supported with Pulseview software on Linux, Mac and WIndows (there's also an Android version, but last I checked it was unstable and terrible.) A couple caveats, to be expected in an entry-level device: It will in fact capture data at the advertised rate, but your USB bus is a limiting factor. If USB performance is short of perfect, you will not realize full speed. This analyzer has a decent set of triggering options, and once triggered essentially grabs a buffer of a specified size, at a specified sample rate, and transfers it to the host PC for analysis. The Pulseview software has a GUI and command-line component, and development libraries. A wide variety of decode functions are implemented, for pretty much every common serial bus protocol and some rather uncommon ones. The command-line component makes it easy to write scripted operations for automated capture and test functions, and the dev libraries make it possible to roll your own GUI and analysis functions, add custom protocol decodes, etc. This is a good tool to have in a kit bag, and at this price point it's an excellent intro tool for beginners and also one that more experienced users can connect to strange or dangerous circuits without fear of damaging a very expensive instrument. It'd be a little nicer if the included wire set came with test clips rather than just header sockets, but it's easy enough to buy a better one and connect it.

I used it to debug a drone battery. It made decoding the codes SO much easier! Cool little device!

It works! Sure, you have to download someone else’s software to use it, but it is quite happy with open source tooling. Great for stalking cross system communication. Decode that oddball LCD communication protocol, or use your laptop as a basic oscilloscope.

Used with testing some serial signals (rs232, rs422, and rs485) and ttl, worked fine with the recommend software I saw in other reviews.

Work great. For the cost, it can't be beat as long as you know how to figure it out because it's not shipped with any instructions.
