    * @brief C++ API for the CJQ4435 MOSFET
    *
    * UPM module for the CJQ4435 MOSFET.  It was developed using the
    * Grove MOSFET module.  A MOSFET is like a switch, but it can
    * switch much faster than a mechanical relay.  Here, we implement
    * support via MRAA's PWM (Pulse Width Modulation) functions.

    * Please note, that the available periods will vary depending on
    * the capabilities of your device.
