Description

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 analyser!

With the growing ubiquity of UART, I2C, and SPI sensors, logic analyzers are becoming a tool everyone needs in their toolbox. While the features of this LA don’t quite measure up against those of, say, the Saleae Logic, it’s still a great tool for quickly diagnosing most communication issues we encounter.

This is an 8-channel logic analyser with support for sampling rates of up to 24MHz. It will work with both 3.3V and 5V systems (up to 5.25V max and 2.0V minimum on a high logic-level). The logic analyser is powered via an included mini-B USB cable.

This logic analyser works with sigrok – an open-source, cross-platform signal analysis software suite. Check out our sigrok PulseView tutorial for help getting started.

The analyser 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 analyser to the female headers.

  • 24MHz/8-Channel USB Logic Analyser
  • 10-conductor female-to-male jumper wires
  • Mini-B USB cable
