    Pros: small, easy to use
    Con: (none)
    Potentiometers for setting maximum voltage and current. With the third potentiometer you can set the currant at which the LED turns from GREEN to RED. This is independent of the maximum current setting.
    I use it for PWM driving a power LED: I set the current to 0.95A, and the voltage a bit above the voltage that is needed for this 0.95A. Hence, the LED is current driven.
