    Digital Discovery                                     The Digilent Digital Discovery™ is a combined logic analyzer and pattern generator instrument that was created to be the ultimate embedded development companion. The Digital Discovery was designed to optimize channels, speed, and portability. The 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. The 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 be any of the below instruments:       24-channel digital logic analyzer (1.2…3.3V CMOS, up to 800MS/s(with the High Speed Adapter)) 16-channel pattern generator (1.2…3.3V CMOS, 100MS/s) 16-channel virtual digital I/O including buttons, switches, and LEDs – perfect for logic training applications Two input/output digital trigger signals for linking multiple instruments (1.2…3.3V CMOS) A programmable power supply of 1.2…3.3V/100mA. The same voltage supplies the Logic Analyzer input buffers and the Pattern Generator input/output buffers, for keeping the logic level compatibility with the circuit under test. Digital Bus Analyzers (SPI, I²C, UART, I2S, CAN, Parallel) The Digital Discovery was designed for anyone embarking on embedded development. Its features and  specifications were deliberately chosen to maintain a small and portable form factor, withstand use in a  variety of environments, and keep costs down, while balancing the requirements of operating on USB  Power.  Digital Discovery   Digital Logic Analyzer   Channels 24   Sample Rate 800 MS/s (with the High Speed Adapter)   Bandwidth 100 MHz+   Voltage Range 1.2V to 3.3V (5V compatible)   Buffer 2Gbit DDR3 acquisition   Bus Analyzers SPI, I²C, UART, CAN, I2S, Parallel and Custom   Digital Pattern Generator   Channels 16   Sample Rate 100 MS/s   Bandwidth 50MHz   Voltage Range 1.2V to 3.3V (5V compatible)   Bus output Counters and Custom   Multi‐purpose Digital I/O   Channels 16   Sample Rate 100 MS/s (50 MHz max output frequency)   Voltage Range 1.2V to 3.3V (5V compatible)   Buffer Algorithmic pattern generator (no buffers used)   Protocol Analyzer   Channels 16‐32   Voltage Range 1.2V to 3.3V (5V compatible)   Bus Analyzers UART send and receive, SPI read and write, I2C read and write     Other Features   Power USB bus powered   User Power supplies 1.2V to 3.3V, available in the two Pmod‐style connectors (100mA max)   Cross‐triggering Between Logic Analyzer, Pattern Generator or external trigger   Data file Import/export using standard formats   Includes USB cable, fly‐wire accessories, high‐speed adapter   Pinout Digital Discovery Specifications  A USB embedded development tool for high speed and multi‐channel applications  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. It's 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.
