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 digital inputs and outputs can be connected to a circuit using simple wire probes or breadboard wires. Comes with Waveforms 2015 software. 

• 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
• Digital Bus Analyzers (SPI, I²C, UART, I2S, CAN, Parallel)
