FYI, This PWM Signal Generator can only be set to a duty cycle of 1 to 100%. After initial test I think it may not be suitable for driving a standard hobby servo as the on time for the hobby servo pulses is 1 to 2milliseconds. This own Signal Generator has a 100th of a second minimum pulse width. It seems to work fine, just that it does not seem to support a typical hobby servo square wave.

This module has 3 frequency ranges. By changing the frequency range to the highest range, it will operate at up to 150KHz (a 6.7 Microsecond, or 0.0000067 second, period). The minimum pulse width can be 1% of this, or 65 Nanoseconds (0.000000067 seconds). The 1/100 second minimum pulse width is only the limit of the slowest frequency range.

    Clean and bright display, has options for external power. Great value.

    This item is very clean and looks good. I could not make this item and put it together at this price. I would review in more detail at a later date. But very nice for the price.

    Just what I needed to control speed on a hybrid stepper/servo motor

    On board regulator allowed 24VDC supply while providing 5v sq 0 to 150khz out. Only change i would make, would be not wrapping around when lowering the frequency. One tick past zero is back to full speed. Could be dangerous. I will probably add a switch to provide full stop rather than try to adjust to zero for safety reasons.
