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

Summary Pros - inexpensive, works well with free open source software Cons - no on board capture buffer, no probes included This 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.

This logic analyzer works perfectly - well worth the cost. It’s compatible with Logic software package and helped solve a rather complex bus protocol I needed to reverse engineer.

Setup & use was quite easy. Software has very nice display of decoded serial data. However, there is no ability to trigger on serial data, or to capture for analysis only the decoded serial data (as opposed to all the dead time between data packets), so the capture buffer fills very quickly with the "nothing" between the data you're interested in. There does appear to be a way to export raw data continuously for offline analysis by some other software (and display it with that other software) but it's up to you to write it. I would give it 5 stars if it was more useful with better software. Admittedly, the vendor says it works with open source software. Just be warned... that software makes doing real work with this tool quite difficult (if not impossible). If I can find better software that makes this really useful I'll update this review with links to it.

I am extremely pleased. I researched and knew what I wanted, what to expect from this little, yet capable, unit. I also understood what not to expects from a $12 piece of hardware. I am not disappointed at all. Configuring it to function with Sigrok's PulseView and Saleae's LOGIC proved just a small ignorance-induced challenge on a Windows 10 x64 newly build workstation, but I was able to get it installed and functioning as intended/desired. It ended up being a pretty shallow learning curve I needed to progress through. Youtube videos and Amazon reviews & buyer question responses helped. User tip: Use Saleae's LOGIC to get the newly connected device configured with drivers, once that is done, try Sigrok's PulseView, prior to trying to force a square peg into a round hole with their Zadiag tool... The unit is very nicely priced, small, and is shipped with the items pictured in the Amazon listing (including the ferrite beaded USB cable (LA has a USB Mini on it)) only. There is no software provided, nor instructions, but, as indicated above, it works with packages that are freely available on the interwebs. The provided test interconnect is a Female to Female configured harness. Tip 2: For use with breadboards and other female-socketed items, I recommend either some male-to-male jumpers or fabricating additional harnesses for use as needed (which I have done - in the attached photo, I show three additional harnesses I made using on-hand supplies I had available - it helps me a lot to have these within easy reach...). if you are in the market for a wallet-friendly Sigrok/PulseView-compatible Logic Analyzer, this may be just what the doctor ordered. Just understand its limitations. The price of the unit doesn't facilitate a super broad bandwidth, noise filtering, or under-/over-voltage protection on the inputs, so one needs to be mindful and work to not exceed published limits (-0.5V to 5.25V). Other than that, and the obvious narrower bandwidth, no negative attributes exist. For the buck, you can't easily beat the bang that this capable little unit brings to the fight. Purchase is recommended. Regarding this OEM/Distributor, HiLetgo hasn't failed me on several technology purchases thus far. Pretty darn happy with them at this time. Take care. -t

Note you will need to download software to use this product. This worked really well for me. I was checking RS422 signals, and it really did a good job with it. I have used it for a few other things now and am still happy with it.

For a professional electronics workbench, particularly when developing custom carrier boards or integrating UART, I2C, and SPI sensors, a logic analyzer is a fundamental requirement. The HiLetgo LA-USB is an affordable, entry-level diagnostic tool that excels at visualizing digital signals and decoding standard protocols. Exceptional Protocol Decoding The primary strength of this analyzer is its integration with open-source software like Sigrok PulseView. It allows you to move beyond simply seeing "pulses" on a screen and actually decodes the data strings (e.g., seeing "0x41" instead of just a series of high and low transitions). This is a game-changer for debugging serial connections between a microcontroller and external sensors, saving hours of manual pulse-counting. Reliable Performance for Standard Use 8-Channel Monitoring: The ability to monitor 8 different digital signals at once is perfect for tracking complex interactions, such as an SPI bus where you need to see MISO, MOSI, CLK, and CS simultaneously. Voltage Versatility: It works reliably with 5V, 3.3V, 2.5V, and 2.0V systems, which covers the vast majority of modern microelectronics and FPGA projects. Buffered Inputs: The inclusion of an internal buffer provides a layer of protection for the device, making it a rugged addition to a busy workbench. Technical Considerations While marketed as a 24MHz device, practical performance has some nuances. For high-speed signals, it is generally best to sample at 4x to 10x the signal rate. In practice, this means the analyzer is rock-solid for signals up to about 2.4MHz to 6MHz. At the full 24MHz sampling rate, you may experience occasional software lockups or data distortion if the USB host controller is busy with other traffic. Ease of Setup and Build Quality Compact and Portable: The small form factor makes it easy to tuck into a field kit or keep permanently connected to a secondary laptop. USB Connectivity: The included USB cable features an EMI ferrite ring, which helps reduce signal noise and improves data integrity during high-speed captures. Standard Wiring: It uses standard Dupont-style connectors, making it simple to replace cables or use custom probe hooks for tighter work areas. Final Thoughts The HiLetgo 24MHz 8-Channel Logic Analyzer is a high-value accessory that perfectly supplements an oscilloscope. It is too inexpensive and useful not to have on your bench, especially when working with microprocessors and digital protocols. While it doesn't replace a high-end scope for analog signal integrity, it is a definitive tool for digital logic verification.

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.

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.

Functionally, this is a very good device for what it is intended, i.e., capturing signals at a low cost. As far as usability is concerened, you do need to get few things done in order to set it up, it would not be too difficult for anyone interested in this device. Thankfully, a lot of information is available on the NET. It is easy to use if you are already familiar with these type of devices, which I think 99% of users who have bought this device would be. If you watch the teardown of this device, it is built quite nicely.

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

Good,It's working I doubted but no problem working fine.

I was working on a digital project where I needed to monitor a data bus of 8 bits wide. Initially, I thought of getting an oscilloscope to debug the circuit, but it wasn't required. This USB logic analyzer is detected as Saleae logic analyzer, and I have installed Logic 2, and it works pretty well.

very worst product, even to pickup nobody is contacting. i ordered twice and received worst product twice
