It is a small, inexpensive, 8-channel device that can capture and continuously stream data with sample rates up to 24MHz to your Windows/Mac/Linux machine for display and analysis.
Martin Thompson also likes , and said: And when you consider that the software decodes UART, SPI, I2C straight onto the waveform display (as overlays), it's a must have for low-speed serial bus debugging.
The unit itself is small and travel-friendly, packaged in a rugged aluminum housing, uses a standard 0.1" header for probe interconnects, and has wonderful support software (Windows, Mac, and Linux OS are all supported).
At 24 MHZ acquisition rate, it's certainly not fast enough to handle external address/data busses on a high-speed modern u P or u C - for that, you need to shell out big bucks for a "real" logic analyzer.
I purchased it shortly after it was released, on the _promise_ that they'd soon have a Mac and Linux client.
