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