Max current: 2A per coil
Microstepping: 1, 1/2, 1/4, 1/8, and 1/16 microstepping
The A4988 driver is a commonly used bipolar stepper motor driver that can provide up to 2A current per coil from 8V to 35V. These drivers are used to drive NEMA 17 motors on the Mill One. This driver also allows for up to 16th microstepping.
Each package comes with three drivers with a small heatsink and header pins installed to be used with the CNC V3.0 Shield or other stepstick type driver shields/control boards.
