DESCRIPTION

This breakout board for the MPS MP6500 microstepping bipolar stepper motor driver has a pinout and interface that are very similar to that of our popular A4988 carriers, so it can be used as a drop-in replacement for those boards in many applications. 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, and the board ships with 0.1″ male header pins included but not soldered in.

 

This product is a carrier board or breakout board for the MP6500 stepper motor driver from Monolithic Power Systems (MPS); we therefore recommend careful reading of the MP6500 datasheet (1MB pdf) before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to approximately 1.5 A per phase continuously without a heat sink or forced air flow (see the Power dissipation considerations section below for more information). Here are some of the driver’s key 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
  • Potentiometer Current Control uses an on-board trimmer potentiometer to set the current limit up to 2.5 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 1.5 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
