Driver module based on the ULN2003 IC in SMD package, integrating 7 Darlington transistor pairs with common emitter configuration. The design enables control of higher current loads such as stepper motors, DC motors, relays and other inductive loads directly from a microcontroller.
Each output includes a flyback diode for protection against voltage spikes generated when switching inductive loads, increasing circuit reliability. Status LEDs indicate the operating state of individual channels. A XH-5P connector is provided for stepper motor connection, commonly used with 28BYJ-48 motors. The module can be used in automation, robotics and actuator control systems based on platforms such as Arduino or other microcontrollers.
