Do you ever get tired of using up an LFO or worse yet a VCO just to clock a module? The Tick solved that. It is a simple clock module kit. It has 3 ranges from fast to glacial, with a cool LED to show the range.
The module puts out a square wave.

This 3HP module has a maximum 20mA current draw. Module depth is 26mm.
