Pololu A4988 Stepper Motor Driver

The Pololu A4988 stepper motor driver drives a bipolar stepper motor and has a maximum output current of 2.2A when cooled.

Properties:

• Simple step control interface
• 5 Step resolutions: full step, 1/2 step, 1/4 step, 1/8 step, 1/16 step
• Adjustable current output for achieving higher step speeds above the rated voltage of the stepper motor
• Intelligent control to automatically switch to the correct power decay: fast decay or slow decay
• Automatic shutdown in case of too high temperatures or too high currents
• Supplied with all surface-mount components, including A4988 driver

The supplied headers still need to be soldered.
