MP6500 Stepper Motor Driver Carrier (Potentiometer 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 re solutions: full, 1/2, 1/4, and 1/8 Uses an on-board trimmer potentiometer for setting the current limit This MP6500 Stepper Motor Driver Carrier (Potentiometer Current Control) is a carrier board or breakout board for the MP6500 stepper motor driver from Monolithic Power Systems (MPS). It 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 airflow (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. It has a pinout and an interface that are very similar to A4988 carriers, so it can be used as a drop-in replacement for those boards in many applications. 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 Two current limit control options available: Potentiometer Current Control & 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 Show more
