    "RPM measurement" would imply that it needs a display too.

    I would use a text LCD and use that to display the control settings and also the RPM.

    Here is a low-cost kit that can do the charge controller function OR the RPM display. I guess you could buy 2 kits to get both functions. Anyway there is free source code there you can use, it might give you ideas;
