The bitcrusher takes an external trigger, which also makes it usable as a sample and hold. The LFO runs from about 0.1Hz up into the audio range at 200Hz with square and triangle outputs. The output section adds LED overdrive and an optional dual mono headphone out. Part of the Shmoergh Moduleur, a full DIY analog synth whose modules also work standalone in any Eurorack case. Split into a core PCB and a UI PCB; the core is mostly 0603 chip parts with JLCPCB gerbers and pick-and-place files, so the surface mount side can be fab assembled.
