Description

This breakout board for the MPS MP6500 microstepping bipolar stepper motor driver is Pololu’s latest stepper motor driver.The MP6500 offers up to 1/8-step microstepping, operates from 4.5 V to 35 V, and can deliver up to approximately 1.5 A per phase continuously without a heat sink or forced air flow (up to 2.5 A peak).This version of the board uses an on-board trimmer potentiometer for setting the current limit.

Features

• Simple step and direction control interface.
• Four different step resolutions: full-step, half-step, 1/4-step,and 1/8-step.
• 4.5 V to 35 V supply voltage range.
• Can deliver 1.5 A per phase continuously without additional cooling.
• Built-in regulator .
• Adjustable current control lets you set the maximum current output.
• Can interface directly with 3.3 V and 5 V systems.
• Over-temperature thermal shutdown, over-current shutdown, short circuit protection, and under-voltage lockout.
