ULN2003 7-Darlington Array - Stepper Motor Driver

The ULN2003 is an array of seven Darlington transistor pairs. With this, a signal can be amplified to 50V and 500mA per channel. The signal pins work with both 3.3V and 5V logic. The built-in flyback diodes protect the chip against inductive loads, such as the coils of an motor.
