The Open Workbench Logic Sniffer is an open source logic analyzer with a USB interface. The hardware is designed for the SUMP open source logic analyzer client and toolchain. This project is a collaboration between the Gadget Factory and Dangerous Prototypes.

Features

• Capture 50MHz+ waveforms on 32 channels
• 200Msps captures up to 100MHz waveforms on 16 channels
• 100Msps captures up to 50MHz waveforms on 32 channels
• 16 buffered channels, 5volt tolerant
• M74LCX16245DTR2G transceiver tolerates voltages from -0.5V to +7V.
• 216K Block RAM supports following memory configurations*
• 8 channels with 24K sample depth
• 16 channels with 12K sample depth
• 32 channels with 6K sample depth
• External clock and trigger input
• Allows interfacing with external test equipment and daisy chaining OLS’s for additional channels.
• Internal clock and trigger output
• 16bit wing expansion header
• USB interface, USB powered
• USB upgradable everything
• Designed for the SUMP logic analyzer client
• Open source
• Low price
• Memory depth is the maximum supported by the hardware, the current firmware implements the following memory depths:
• 8 channels with 16K sample depth
• 16 channels with 8K sample depth
• 32 channels with 4K sample depth

Future firmware upgrades will support the maximum memory configurations.
