The Logic Pirate is an inexpensive, yet capable open source logic analyzer. It can sample 8 channels at 20 million samples per second, and may be overclocked for even faster acquisitions. It's designed to support the open source SUMP logic analyzer protocol with software available for most operating systems.
256,000 Samples recording size
20 MHz sampling speed, can potentially be overclocked to 60 MHz
No compromise on sample size when combining different speeds or number of channels
Simple configurable edge detection triggers on all inputs (simple OR trigger)
Configurable ratio of samples from before and after the trigger (rolling sample buffer)
5 V tolerant inputs (LOW-level voltage < 0.8 V, HIGH-level voltage > 2.0 V)
About 500 kB/s transfer speed to the PC (256 kSamples take about 0.5 seconds)
Data capturing can be stopped from the host software anytime
Cross platform host software for Windows, OS X, and Linux
DIY-friendly 0603 parts and SOIC packages used on a 2-layer board
On board 3.3 V regulator can supply up to 400 mA to an external circuit
