MP6500 Stepper Motor Driver Carrier (Digital Current Control)

• Adjustable current, step and direction control for one bipolar stepper motor
• Operating voltage: 4.5 – 35 V
• Continuous current per phase: 1.5 A
• Logic voltage: 2.1 – 6 V
• Microstep resolutions: full, 1/2, 1/4, and 1/8
• Allows for dynamic current limit control through a pair of digital inputs

This MP6500 Stepper Motor Driver Carrier (Digital Current Control) 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. The board ships with 0.1″ male header pins included but not soldered in.

This version of the MP6500 Stepper Motor Driver Carrier offers digital current control through its I1 and I2 inputs, which allows a microcontroller to make dynamic current limit adjustments.

Features

• Simple step and direction control interface
• Four different step resolutions: full-step, half-step, 1/4-step, and 1/8-step
• Adjustable current control lets you set the maximum current output, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates
• Digital Current Control
• Internal current sensing allows the driver to automatically adjust the decay mode as necessary to provide the smoothest current waveform
• Built-in regulator (no external logic voltage supply needed)
• 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
• 4-layer, 2 oz copper PCB for improved heat dissipation
