This is a DC 5V, 4-phase, 5-wire stepper motor with a Stepper ULN2003 driver board.
The ULN2003 is one of the most common motor driver ICs that houses an array of 7 Darlington transistor pairs, each capable of driving loads up to 500 mA and 50 V.
Basically, a Darlington pair is a pair of transistors where the second transistor amplifies the output current of the first transistor. 5-wire phase can drive an ordinary ULN2003 chip and can also be connected as phase 2 may be supporting the development board with a direct plug and an easy-to-use stepper motor used in the development board.
