Digital Discovery Specifications

The Digilent Digital Discovery™ is a combined logic analyzer and pattern generator instrument that was created to be the ultimate embedded development companion. Digital Discovery was designed to optimize channel number, speed, and portability. A small form factor facilitates easy storage and provides a whole suite of advanced features to allow you to debug, visualize, and simulate digital signals for most embedded projects. Its digital inputs and outputs can be connected to a circuit using simple wire probes or breadboard wires; alternatively, the Digital Discovery High Speed Adapter and impedance-matched probes* can be used to connect and utilize the inputs and outputs for more advanced projects. The Digital Discovery is driven by the free WaveForms software and can be configured to any combination of power supplies, logic analyzer, pattern generator, static inputs and outputs, and protocol analyzer.

*Note: The High Speed Adapter and High Speed Logic Probes are an optional add-on at checkout. You can also buy them separately as an accessory. (Pinout)
