   * @brief UPM module for the ULN200XA Darlington Stepper Driver
   *
   * This module was developed on a ULN2003A Stepper Driver. It
   * should also support the ULN2001A, ULN2002A, and ULN2004A devices, when
   * using to drive the 28BYJ-48 unipolar stepper motor.
   *
   * Vcc goes to the 5V pin on your development board and the Vm pin should
   * be connected to an external 5V supply.
