Title: Very cheap logic analyzer
Post by: jeanmarc78 on October 04, 2014, 04:07:18 pm
Hello,

I have found a very cheap (14$) 8 channels 24 MHz logic analyzer :
http://http://www.hotmcu.com/saleae-24mhz-8channel-logic-analyzer-p-28.html?cPath=3_26

It seems it is a clone of the Saleae Logic.

With the Saleae Logic PC software (http://https://www.saleae.com), we have a very powerfull tool which is able to decode many protocols (I2C, SPI, Async, ...).

Very useful for debugging microcontroller firmware with a small budget.

These are likely fakes, not clones.  Consider supporting the small company that designs and makes them.

I think they are still clones, as they use the same chip an much of the design as the original.

If you want a cheap logic analyzer I would suggest the logic shrimp (v2) or the logic analyzer.

Yes, it's clone. The main chip is CY7C68013A, a 8051 core with USB.  A bare bone board is cheaper.

You can even get a cheaper one.

Instead of supporting clones, try this:
