I noticed there seem to be two types of the cheap logic analyser. One has two ground pins and the other has a CLK pin and a single ground pin. According to one Amazon listing the type with the CLK pin is the old type. Does anyone have the old type with the CLK pin and knows if this is a clock output or input and if it could be used to sync to a scope trigger or a system clock? Unfortunately the one I received today has the two ground pins on the label, so I’m wondering if its worth trying again for the version with CLK.
