An improvement over its predecessor, the Stepper 2 Click Board™ from MikroE is another addition in the range of motor driver Click Boards™. Complete with an A4988 microstepping motor driver, the Stepper 2 Click Board™ surpasses the original Stepper Click Board™ with an output drive capability of up to 35V and 2A.
Not just power, the new version is designed to offer users more control (precision). It can go down to 1/16th of a step to drive the motor. The board features three pairs of onboard screw terminals for secure connectivity. The first two (2B, 2A; 1A, 1B) are for connecting the motor while the third pair (VIN and GND) is for an external power supply (minimum 7V).
The Stepper 2 Click Board™ is intended to operate bipolar stepper motors in full-, half-, quarter-, eighth-, and sixteenth-step modes. The user can select between the different stepping modes (steps and micro-steps) using a set of three (J1-J3) onboard jumpers. Stepper 2 Click Board™ uses MikroBUS EN, RST, SL, ST and DIR pins to communicate with the target board microcontroller. It is designed to work with a 3.3V power supply but is also compatible with a 5V logic level.
