HiLetgo USB Logic Analyzer Device With EMI Ferrite Ring USB Cable 24MHz 8CH 24MHz 8 Channel UART IIC SPI Debug

I download and installed the Logic 2.4.22 logic analyzer software on a laptop, connected the logic analyzer cables to my test circuit and I was pleasantly surprised at how very well the software and hardware interfaced to display very useful timing graphs. My troubleshooting needs are met for now.

Works as expected! Make sure to install the driver before using it in pulseview. Mine initially showed up as unknown device.

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.

Overall, it works great and is not super difficult to set up. 24MHz is pretty low for comms analysis, but for $12, this is a no-brainer.Some helpful points in addition to what others have already pointed out:-You may have to try different USB ports in order to get the Zadig installed drivers to work. I had the same problem as the other reviewer with my Dell Inspiron 15-- only some of the USB 2.0 ports work properly with this device.-After using the Zadig utility, you may need to restart Sigrok Pulseview once or twice, and then you'll notice that the driver gets detected automatically with a sound confirmation when the app opens.-You should see the device automatically recognized as "Saleae Logic". If you try to set up the driver in Pulseview manually, your choices are Saleae Logic 16 and Saleae Logic Pro or something similar. Try to get the drivers to be recognized automatically.

So far I have used this to troubleshoot several designs and I has provided excellent data to help me resolve issues in the design. It doesn't play well with other devices on the USB system though. I attempted to operate a serial connection through USB to monitor data and the analyzer did not function correctly. It was fine when I disconnected the serial monitor. I am suspecting there is a setting on my system that needs adjusting to get it to work properly. I do not fault the analyzer. Great product.

This is amazingly simple and powerful tool. Worth every cent.All you need is PulseView & Zadig WinUSB driver, it gets recognized as Saleae Logic.

Hasta ahora ningún reclamo por el uso de los mismos. Buena calificación

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.
