MP6500 Stepper Motor Driver Carrier, Digital Current Control Pololu 2968

• 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
• Two current limit control options available:
  • Potentiometer Current Control — this carrier version uses an on-board trimmer potentiometer to set the current limit up to 2.5 A
  • Digital Current Control — this carrier version allows a microcontroller to dynamically adjust the current limit up to around 2 A
• Internal current sensing allows the driver to automatically adjust the decay mode as necessary to provide the smoothest current waveform
• 4.5 V to 35 V supply voltage range
• Can deliver 1.8 A per phase continuously without additional cooling
• 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
• Exposed solderable ground pad below the driver IC on the bottom of the PCB
• Module size, pinout, and interface match those of our A4988 stepper motor driver carriers in most respects
