USB Logic Analyzer - 24MHz/8-Channel

Is your I2C bus not ACK'ing the way you expect? Do you need to discover a UART's mysterious baud rate? Or do you want to reverse engineer an SPI protocol? These all sound like jobs for a logic analyzer! With the growing ubiquity of UART, I2C, and SPI sensors, logic analyzers are becoming a tool everyone needs in their toolbox or on their workbench. This 8-channel USB Logic Analyzer with support for sampling rates of up to 24MHz provides a good while economic option making it a great tool for quickly diagnosing most communication issues we encounter.

These analyzers will work with both 3.3V and 5V systems (up to 5.25V max and 2.0V minimum on a high logic-level) and is powered via an included USB-C cable. This logic analyzer works with PulseView -- an open-source, cross-platform signal analysis software suite.

The analyzer ships with Female-To-Female jumper wires. If you're using an Uno or board with female headers we recommend picking up a handful of Male-To-Male jumpers to connect the analyzer to the female headers.

Note: On some units the GND connection that's adjacent to input six isn't actually a ground, it appears to be some sort of clock signal. We recommend not using that pin for anything just to be safe.

One of the GND pins in not connected.

If anyone is running into issues using this device try using the other GND pin and see if that works.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

    one of the ground pins is definitely not ground

  • I've found the probe signals seem to be pulled up to 3.3v. This is messing with some of my existing circuit. Any way to disable this?

  • The includes tab says "10-conductor Female-to-Male Jumper Wires". It's actually Male-to-male as it says on the description tab.

this thing is fabulous - and the open source sigroc works great!

I dearly love my 'scope. But sometimes ... I2C, some crazy display .. that's when this tool is the thing. I can't believe it's so cheap for the stuff it does. OK, it's limited to 25MHz - well, I don't work on repairing any Cray supercomputers, so that's OK.

SPI, I2C - this is the cure for pain.

I am impressed

I am truly impressed by this little logic analyzer.
