(5pcs/lot) A4988 Stepper Motor Driver+ Heatsink For 3 D Printer,Reprap,RAMPS1.4 for arduino

This pack of five A4988 stepper motor drivers with heatsinks is an essential component bundle for 3D printers, RepRap builds, and RAMPS 1.4 projects. Designed for students, makers, and CNC hobbyists, these drivers simplify bipolar stepper motor control using a straightforward step and direction interface. They offer an efficient way to run your motors without overloading your microcontroller.

Simple step and direction control

The built-in converter translates a single pulse on the step input into a micro-step, eliminating the need for complex phase sequence tables or high-frequency control lines. This makes the A4988 driver ideal for projects using microprocessors with limited processing capacity.

Five versatile microstepping modes

Achieve smooth and precise motion control with five selectable step resolutions, including full, half, quarter, eighth, and sixteenth-step modes. This flexibility allows you to easily configure your bipolar stepper motor's performance.

High voltage and current capacity

These drivers support bipolar stepper motors with an output drive performance of up to 35 V and plus or minus 2 A. The package includes dedicated heatsinks to help manage thermal dissipation during operation.

Adjustable current output

An on-board adjustable potentiometer allows you to set the maximum current output, which can help achieve higher step rates. The driver also features automatic current decay mode detection and selection, operating in slow or mixed decay modes.

Comprehensive circuit protection

Guard your electronics against damage with built-in thermal shutdown, undervoltage lockout, and cross-current protection. The board also features ground short-circuit and load short-circuit protection to ensure safe operation.
