A4988 Stepper Motor Driver Carrier, Black Edition

Our Black Edition A4988 stepper motor driver carrier is a higher-performance drop-in replacement for the original A4988 stepper motor driver carrier. It features a four-layer PCB for better thermal performance, allowing the A4988 microstepping bipolar stepper motor driver to deliver approximately 20% more current than our two-layer version. Like our original carrier, the Black Edition offers adjustable current limiting, overcurrent protection, and five different microstep resolutions. It operates from 8 – 35 V and can deliver up to 2 A per coil with sufficient additional cooling.
