Bargain logic analyzers: setup, teardown and comparisons.

A rabbit hole of logic analyzers... that's what I’ve been down in the last couple of weeks!!

I recently bought a cheap logic analyzer from Aliexpress and was super impressed with its performance. I made a video showing how it worked using I2C and one-wire bus examples, the video generated a lot of comments.

This video is somewhat of a follow-up showing how to set the device up using Zadig and Pulseview, I also do a teardown to show what's inside. Finally, these cheap Saleae clones are not the only low-cost option for the hobbyist; I setup a Pi Pico as a logic analyzer and compare its performance to the Saleae clone.

Overall, I'm still impressed with the bargain Saleae compatible device from AliExpress, for the bargain price it's a versatile tool for any hobbyist!

The cheapest seller on AliExpress that I could find for the Saleae compatible device is linked below; however, the device looks slightly different from the one I used in the video, it also has only 55 reviews, so buyer beware:

TZT USB Logic Analyzer 24MHz 8 Channel 24M/seconds Logic Analyzer

For the exact version I used in the video the link below is to a slightly more expensive unit that has more sales and more positive reviews (I guess only the case is different, I suspect the hardware is the same for all these cheap analyzers):

There are a few other components I highly recommend:
