DRV8825 Stepper Motor Driver with Aluminum Heat Sink

DRV8825 Stepper Motor Driver with Aluminum Heat Sink is a carrier board or breakout board for TI’s DRV8825 stepper motor driver; we therefore recommend careful reading of the DRV8825 datasheet before using this product. This stepper motor driver lets you 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 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)
• 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 (V): 8.2 to 45
• Current Handling Capacity: 2.2 A (Max.)
• Continuous Current (A): 1.5 (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 (mm): 15
• Width (mm): 20
• Weight (gm): 4

Package Includes:

• 1 x DRV8825 Stepper Motor Driver with Aluminum Heat Sink
