DRV8825 Stepper Motor Driver Module

The DRV8825 stepper motor driver carrier board TI DRV8825 micro bipolar stepper motor drive is a breakthrough. The module has a pinout and interface with our A4988 stepper motor driver carrier is almost the same, so it can be used as a better performance of the pull-down menu board replacement in many applications. DRV8825 features an adjustable current limit, overcurrent and overtemperature protection, six micro-resolution (down 1/32-step). It uses 8.2 – 45 V, can provide up to about 1.5 per phase no heat sink or forced air flow (rated up to 2.2 per volume sufficient additional cooling).

Features:

• A simple steps and direction control interface.
• Six different steps resolutions: full step, half step, 1/4-step1/8-step1/16-step, 1/32-step.
• Can interface directly with 3.3 V and 5 V systems.
• Over-temperature thermal shutdown, overcurrent shutdown, undervoltage lockout.
• Short to ground short circuit load protection.
• 4 Layer 2 oz copper PCB, in order to improve heat dissipation.
• Exposed solder ground below the bottom of the driver IC on the printed circuit board pad.
• Module size, pin and interface matching A4988 stepper motor driver operators in many ways.
• Adjustable current control lets you set a potentiometer, which lets you use the stepper motor’s rated voltage or more, in order to achieve a higher rate of maximum output current step.
• Intelligent chopping control automatically selects the correct current decay mode (fast decay or slow decay).
• Maximum 45 V supply voltage.
• built-in voltage regulator (the need for any external logic supply voltage).

Parameter:

• Size: 1.5mmX2mm (same as 4988)
• Drive current: 2.5A
• Subdivision: 1,1 / 2,1 / 4,1 / 8,1 / 16,1 / 32
• Manufacturing process: SMT placement machine manufacturing, non-manual welding, higher yield, more stable performance.

Suitable for:

• Need to drive stepper motor occasions.
• Is to build 3d printer, cnc, engraving machine and other essential modules.
• Supported 3d printers are Prusa Mendel, ultimaker, printbot, makerbot and so on.
