Product information "Pololu A4988 stepper motor driver, Black Edition"

Our Black Edition A4988 stepper motor driver carrier is a higher performance drop-in replacement for the original A4988 stepper motor carrier. It features a four-layer PCB for better thermal behaviour, allowing the A4988 bipolar microstepping stepper motor driver to deliver around 20% more current than our two-layer (green) version. Like our original carrier, the Black Edition offers adjustable current limiting, overcurrent and overtemperature protection and five different microstep resolutions. It operates from 8 V to 35 V and can supply up to 2 A per coil with sufficient additional cooling. The circuit board is supplied with 0.1" connector pins that are not soldered in.
