MIKROE-2035

ULN2003 Linear Regulator Click Board

**Stepper 3 click is a mikroBUS** add-on board for driving unipolar stepper motors with precise controls individual motor phases can be accessed separately.

Features:

* ULN2003 High-Current Darlington transistor array

* Connector for external power supply up to 30V

* Interface: INA-IND in place of AN, RST, CS, PWM

* 5V power supply

* * Precise motor control: individual phases can be accessed separately

Ready-to-use examples save development time

* Works in all MikroElektronika compilers

The board carries a Texas Instruments ULN2003 High-Current Darlington transistor array for operating the motors.

Motors are connected through a 4-pin male connector on the top of the PCB. They can be driven by the click board"s own power supply, or with an external power supply which can be brought through onboard screw terminals up to 30V.

Stepper 3 click communicates with the target board MCU through mikroBUS™ PWM, AN, RST and CS pins here used for individual motor phases, marked INA, INB, INC, IND.

The board is designed to use a 5V power supply only.
