Around 2015 the Open Bench Logic Sniffer looked like a really promising logic sniffer/analyzer at a price a hobbyist could tolerate. These were available assembled from Seeed (and others?) There's no sign of it today that I can find. Is there a successor that obsoleted this? Is there a competitively priced commercial offering that is a good substitute?
Not that I really want to build one, but I can't find board layout files (KiCAD or other) or gerbers, even though the project is described as open source. The code files are there, but not schematics and board layout.
