A4988 DRV8825 3D Printer Parts

 

DRV8825 3D Printer Part:

 

The DRV8825 Stepper Motor Driver Carrier is a breakout board for TI’s DRV8825 microstepping bipolar stepper motor driver. The pinout and interface of the module are basically the same as our A4988 stepper motor driver carrier, so it can be used as a high-performance drop-in replacement for these boards in many applications.

The DRV8825 has configurable current limiting, overcurrent and overheat protection, and six microstep resolutions (down to 1/32-step). It operates from 8.2 to 45 V and can produce up to 1.5 A per phase without the use of a heat sink or forced air flow (Designed for up to 2.2 A per coil with plenty of additional cooling).

Key Product Features:

• Interface for simple step and direction control.
• There are six distinct resolutions for steps: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step.
• Interfaces with 3.3 V and 5 V systems directly.
• Thermal shutdown due to overheating, overcurrent shutdown, and under-voltage lockout.
• Protection against short-to-ground and shorted-load.
• Heat dissipation is improved using a 4-layer, 2-ounce copper PCB.
• On the bottom of the PCB, there is an exposed solderable ground pad beneath the driver IC.
• In most ways, the module size, pinout, and interface are identical to those of our A4988 stepper motor driver carriers.
• With an adjustable current control, you can use a potentiometer to set the maximum current output.
• Allowing you to use voltages higher than the rated voltage of the stepper motor to obtain higher step rates.
• Intelligent chopping control that determines the appropriate current decay mode automatically (fast decay or slow decay).
• The maximum supply voltage is 45 V.
• Integrated regulator (no external logic voltage supply needed).

A4988 3D Printer Part:

This is a breakout board for Allegro’s A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection; before using this product, please carefully read the A4988 datasheet. With an output drive capacity of up to 35 V and 2 A, you may operate bipolar stepper motors in full-, half-, quarter-, eighth-, and sixteenth-step modes.

 

The translator is critical to the A4988’s straightforward implementation. Simply sending one pulse to the STEP input causes the motor to move one micro step. It is not necessary to program phase sequence tables, high-frequency control lines, or sophisticated interfaces. The A4988 interface is an excellent choice for scenarios in which a complicated microprocessor is either unavailable or overwhelmed.

Key Product Features:

• Interface for simple step and direction control;
• There are five different step resolutions: whole, half, quarter, eighth, and sixteenth.
• Adjustable current control allows you to set the maximum current output with a potentiometer, allowing you to use voltages higher than the rated voltage of the stepper motor.
• To reach larger step rates, increase the voltage.
• 3.3 and 5 V logic supply compatibility
• Intelligent chopping control that determines the appropriate current decay mode (rapid or slow decay) automatically;
• Thermal shutdown due to overheating, under voltage lockout, and crossover-current protection.
• Protection against short-to-ground and shorted-load.
