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.
