QuiteSmallLFO: Square/ramp LFO (2HP)

This is another shrinkified version of an old 4HP module (and, briefly, a 1U tile) - a square/ramp LFO.

Nothing fancy, especially given the limitations of the 2HP form-factor but if you want a steady square/pulse and a saw/triangle wave then this module has you covered. Controls are simple - there's a rate switch for toggling between 'very slow' and 'not quite so slow' modes, plus an attendant pot for adjusting the aforementioned rate, plus a 'shape' pot which will modify not only the shape of the triangle output from saw to triangle to reverse saw, but it will also modify the duty cycle of the square wave output as well (the circuit is basically a relaxation oscillator and a comparator ...)

This module is not voltage controlled, although with a bit of judicious hackery this could be changed. Besides, a simple firmware fix will turn the TinyDVCO into a voltage-controlled LFO.

Works well as modulation source, obviously, but also very handy if you need a simple clock-type module without a whole load of fuss and bother.

NOTE: this module uses a couple of components that I don't routinely keep in stock (specifically, the switches and the TS321 op-amps) so there may be a lead time of a few days if I need to source additional stock.

2HP wide, supplied with power cable and Euro-to-JST connector.
