## 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 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 mini-B USB cable. This logic analyzer works with [sigrok](https://sigrok.org/) – 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](https://core-electronics.com.au/search/?q=12795) to connect the analyzer to the female headers.

You can also pickup a [Bus Pirate Probe Set](https://core-electronics.com.au/bus-pirate-basic-probe-set.html) if you want to have even easier access to probes for prototyping.
