This ULN2003 Driver Board is designed to operate small stepper motors at voltages between 5V and 12V, at a maximum current of 500mA. It is Arduino compatible and is typically used with Arduino UNO boards, but often requires a separate power supply to avoid damaging the Arduino board.
This set is a perfect choice for building your own 3D printer or CNC machine. The Driver board could function as a driver for other devices as well, as listed below in the " ULN2003 Chip Features". It is pretty self-explanatory that buying this set would be a very wise choice.
