This is my go-to super inexpensive logic analyser for simple Raspberry PI Pico or ESP32 hardware projects where using blinking LEDs are just not sufficient—- works very well with saleae’s software —- BTW the software also detects 2 of these logic analyzers correctly —- but they can not be used concurrently.

To clarify, it isn't the device itself that works on Windows. What you receive is the module, 8 DuPont wires, and a USB cable. You are on your own from there. Attempting to get the Sigrok PulseView interface running on Ubuntu did not go well. The Windows installed worked as expected and Zadig is included in the installation directory if there is a USB driver problem. Once installed I hooked three channels to Pico PWM pins and could easily see the duty cycles as I varied the the duty_u16 parameters.For the money it is a valuable trouble shooting tool.

I attached this logic analyzer to an old modem's UART and was able to capture the modem's boot process using PulseView. The device was recognized as 'Saleae'.This is a great device for hobbyists: basic, simple and very affordable. I am happy with this purachase

Works very well and unbelievable value. I couldn't imagine that for $12.00 I could get a useful logic analyzer. But I gave it a try based on the other positive reviews and it's amazing.There's absolutely no documentation except for listing their support email address, not even a web URL. But don't worry, just download the PulseView software and follow those instructions. Up and running perfectly in under 10 minutes on my OSX desktop. I just plugged the supplied cable into my USB hub and attached a few of the colored signal wires into my project breadboard.It captured the SPI bus from my Arduino project and I was able to spot the problem immediately. PulseView comes with a huge number of protocol decoders built in including one for SPI that I used.The UI is unbelievably responsive for something that is handling millions of data samples. Instantaneous and fluid zooming and scrolling.As expected it has a flexible Trigger function that captured my the signals at exactly the point in time I needed to investigate. I wish I had bought this weeks ago, it would have saved me a lot of debugging time already.If you're interfacing to Arduino, RaspberryPi or doing any type of digital logic breadboarding I'd highly recommend getting one of these ASAP.

SummaryPros - inexpensive, works well with free open source softwareCons - no on board capture buffer, no probes includedThis is a good little logic analyzer for the home hobbyist or even a small development team. The hardware uses a CY7C68013A microcontroller (an 8051 MCU core with an integrated USB 2.0 interface). It comes with a USB A to mini USB B cable and some short jumpers wires. It is powered by USB so there is no other power supply to deal with.There is no on board capture buffer so your computer needs to be fast enough to receive the data as it comes over USB. With most systems that shouldn’t be an issue providing you are not doing any other intensive tasks, particularly those that use USB, at the same time. Trying to run all 8 channels at 24Mhz though could be an issue on some systems.Looking at the board, there isn’t any input buffering other than series resistors. Care must be taken not to expose the channel inputs to voltages that could damage the on board microcontroller.There is no software included, but one can download the open source sigrok/PulseView which fully supports this device. I tested it with PulseView 0.4.1 on a Windows 10 system and it was recognized as “Saleae Logic” analyzer (an older name brand analyzer). The only part that could be slightly tricky to getting PulseView working is installing the WinUSB driver using Zadig. If you are unfamiliar with Zadig, you can read about it on the sigrok wiki area for windows.Since this board emulates a “Saleae Logic”, there are also commercial software offerings that should work with it.I did an initial test using two channels simultaneously reading a 115200 bps data stream (sample rate set to 500kHz) and it worked flawlessly. PulseView easily decoded the ASCII data once configured. I again captured the same stream setting at 24Mhz (which is way over sampled for the data stream) just to see what it would do, and it worked fine showing the much more frequent sample rate.I’m not aware of a way to setup anything but a simple trigger to start/stop capture using PulseView. That is a software limitation if you are trying to catch a more complex event that occurs infrequently.The jumper wires that came with it are of limited use unless you always have available header pins to connect to in your circuit (doubtful). I suggest ordering a set of “logic analyzer test clips” to complete your setup.
