Great for circuit bending projects.

It does the job. The only reason I gave this 3 stars is that the precision knobs aren't something you can turn without a screwdriver. The one I installed in my Kawai X30 stopped working, but there's a chance I might have over volted it and broke it somehow, because when it quit working the LTC1799 chip itself was very hot to the touch.

Needs documentation. The cited data sheet is insufficient.The circuit card has 3 jumpers, two potentiometers and 3 Jumpers, but no information on what function each of them performs ( such as what pins to connect power to, which is the output and how do the potentiometers correspond to the ones shown in the IC data sheet.

Pretty good.I wish it had extra holes for wires to replace the pots. The trimmer holes are so small.

I bought the oscillator module to use as a continuously-variable clock input for PIC microcontollers, specifically for the 1 MHz to 20 MHz range. I will typically be using the clock with 3.3V power, which is lower than the optimum 5V required for highest performance. Even at 3.3V, the module outputs a stable square wave that is perfect for the PIC clock input. This allows me to continuously vary the execution speed of a complex program over a wide range. Initially, I am looking for transformer resonances in an inverter driver program which can independently vary duty cycle. For my purposes, the screwdriver adjusted pots are not a problem. Well worth the money for me. With a 3.3V supply, the module can operate at 33 MHz, but essentially with a sine wave output. This is consistent with the date sheet for the IC used. In that case, operation at 5V is probably required.
