Stepper 2 click carries a A4988 microstepping motor driver along with screw terminals for connecting a motor and a required external power supply (minimum 7V). The output drive capacity of the motor is up to 35V and ±2A. The A4988 chip is designed to drive bipolar stepper motors in full-, half-, quarter-, eight-, and sixteenth-step modes. A set of three onboard jumpers (J1-J3) allow you to switch between the different stepping modes. The board communicates with the target MCU through EN, RST, SL, ST and DIR pins (corresponding to AN, RST, CS, PWM and INT pins of the default mikroBUS configuration). The click is designed to run on 3.3V power supply only.
