Mikroelektronika MIKROE-1926 Stepper 2 Click Board - A4988 Stepper Motor Driver, ±2A, 35V

Technical description of the product (MIKROE-1926):

The Mikroelektronika MIKROE-1926 Stepper 2 Click Board is a complete solution for driving bipolar stepper motors with full/half and micro-steps. It features the A4988 IC from Allegro Microsystems with DMOS low RDSON drivers on its outputs, which ensure high efficiency and reliable operation of the internal H-Bridges. This IC has the integrated translator section, used to simplify the control: using simple step control inputs from the host MCU, the stepper motor can be driven in both directions, with the predetermined step sizes. In addition, the output current is regulated allowing for noiseless operation of the stepper motor, with no resonance and ringing typically observed at unregulated stepper driver designs. It is ideal for applications that require precise and reliable stepper motor control, such as the movement control of beds, heads, and assemblies of various CNC plotting, milling, and 3D printer designs. Micro-steps: 1, 1/2, 1/4, 1/8, 1/16. Interface: GPIO. Input voltage: 3.3V. Compatibility: mikroBUS. Size: M (42.9 x 25.4 mm).
