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 whilst 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 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. Set up the USB Logic Analyser with Pulseview Features * 8-channels * Sampling rate up to 24MHz, configurable down to 20kHz * 5.25V maximum voltage input * 2.0V minimum logic-high * 0.8V maximum logic-low * Input impedance > 100kΩ, 5pF * USB power supply * USB Type C Connector * Supports open-source sigrok logic analyzer software * Cross-platform support: Windows, Mac OS X, Linux, Android, etc. * Dimensions: 54.7 x 27.4 x 14.1 mm With this latest revision of the USB Logic Analyzer, the USB Mini B connector was replaced with a more up-to-date USB Type C connector.
