    Is anyone using a Super-PID router speed controller with a TinyG? The TinyG outputs PWM and the Super-PID uses that as in input, so I assume it would work, but the Super-PID also allows the spindle to be turned on by the controller too, but it looks like it expects 5V and the TinyG outputs 3.3V, I believe.

    Page 23 of their manual shows how a PC would be hooked up. http://www.vhipe.com/product-private/SuperPID-v2_Instructions.pdf

    So, I was wondering if anyone has this combo working before I buy one.

    Thanks

    First I have seen of Super-PID.

    My read of the instructions is that SuperPID will turn the PWM output back into s DC voltage, mimicking the wiper on the POT.

    Buffer your tinyG PWM 3.3v Output to 5V and your should be good.

    You might find this useful for calibrating once you are done:

    I’ve used a Super-PID before – great unit. I asked the same question of the manufacturer way back when.

    The instructions are clear: “Super-PID can directly accept a speed control voltage of 0v to 5v ”

    So, it can directly accept between 0 and 5V – 3.3V is between 0 and 5V.

    You won’t have a problem.

    If the filtered PWM output is 3.3V max, won’t the Super-PID be limited as to Max RPM output?
    Or is there a second calibration on Super-PID that translates 3.3V to mean max RPM?
