DRV8825 Stepper Motor Driver Module with Aluminum Heat Sink

The DRV8825 Stepper Motor Driver with Aluminum Heat Sink is a breakout board for TI’s DRV8825 micro-stepping bipolar stepper motor driver.

The module has a pinout and interface that are nearly identical to those of the A4988 stepper motor driver carriers, so it can be used as a higher-performance drop-in replacement for those boards in many applications.

The DRV8825 features adjustable current limiting, overcurrent, and overtemperature protection, and six micro-step resolutions (down to 1/32-step). It operates from 8.2 – 45 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (rated for up to 2.2 A per coil with sufficient additional cooling).

Note: We are supplying two DRV8825 Drivers as DRV8825 Stepper Motor Driver with Aluminum Heat Sink- Good Quality and DRV8825 Stepper Motor Driver with Aluminum Heat Sink- Normal Quality. The difference between them is, the good quality DRV8825 has more PCB layers and it features the connecting pins which are of gold plated as compared to others.

Using the Driver

Technical Specifications:

• Microstep resolutions: full, 1/2, 1/4, 1/8, 1/16, and 1/32.
• 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. Hence 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

Package Includes:
