This module can drive one stepper motor. Use this board to control your stepper motor from your microcntroller, Arduino, RaspberryPi, etc. It uses the hugely popular Texas Instruments DRV8825 IC. The stepper motor can be controlled through just 2 pins - one for direction and the other for speed and step control. This makes it easy to control the speed and position of the motor from a microcontroller, Arduino, Raspberry Pi, etc.
It offers numerous features like features adjustable current limiting, over-current and over-temperature protection, and six different microstep resolutions (down to 1/32-step). It can drive stepper motors with an input voltage of 8V to 45V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (it is rated for 2.2 A per coil with sufficient additional cooling).
- Popularly used for controller Stepper motors for 3D Printers
- Maximum Operating Voltage: 45V
- Maximum Continuous Current: 1.5A per phase
- Maximum Current with Heatsink and Air Cooling: 2.2A per phase
- Simple step and direction control interface
- Six different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step and 1/32
- Compatible with 3V3 and 5V microcontrollers
- Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates
- Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
- Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection
Note: The DRV88525 Stepper Motor Driver is a new replacement for the A4988. It can handle more voltage and current for the stepper motor compared to the A4988.
