    Is it possible to generate a variable pulse signal of 0 - 10 kHz using the 4 Channel USB Relay Module?

    I am thought I would be able to control something with variable voltage from the GPIO, but I need 0 - 10V to achieve the full range.

    Hello Erin,

    It is not possible to generate 10KHz signal simply by toggling the GPIO. This is because USB CDC protocol implementation on this device cannot transport commands fast enough to toggle IOs at that rate.

    Thanks,
