POLOLU-2128 A4988 Stepper Motor Driver Carrier, Black Edition POLOLU

Description

POLOLU-2128 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 (green) version. Like our original carrier, the Black Edition offers adjustable current limiting, over-current and over-temperature protection, and five different microstep resolutions. It operates from 8 AND V to 35 AND V and can deliver up to 2 AND A per coil with sufficient additional cooling. This board ships with 0.1 AND Prime male header pins included but not soldered in.
