DRV8825 Stepper Motor Driver with Aluminum Heat Sink

The DRV8825 Stepper Motor Driver with Aluminum Heat Sink is a carrier board or breakout board for TI€™s DRV8825 stepper motor driver. It allows you to control one bipolar stepper motor at up to 2.2 A output current per coil.

  Features:  

• Simple step and direction control interface
• Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step
• Adjustable current control allows you to set the maximum current output with a potentiometer, enabling the use of 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)
• 45 V maximum supply voltage
• 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, and under-voltage lockout
• Short-to-ground and shorted-load protection
• 4-layer, 2 oz copper PCB for improved heat dissipation
• Exposed solderable ground pad below the driver IC on the bottom of the PCB

  Specifications:  

• Supply Voltage: 8.2 to 45 V
• Current Handling Capacity: 2.2 A (Max.)
• Continuous Current: 1.5 A (per phase)
• Logic Input: 2.5 to 5 V
• Microstep Resolutions: Full, 1/2, 1/4, 1/8, 1/16, and 1/32
• Reverse Voltage Protection: No
• Length: 15 mm
• Width: 20 mm
• Weight: 4 gm

  Package Includes:
