Oem DRV8825 stepper motor controller

Все о продукте

The DRV8825 is a Texas Instruments stepper motor driver module for Arduino. Its pinout is the same as the popular A4988, but it can deliver up to 1.5A of current and operate in 1/32 microstep mode, making it extremely quiet and stable. It also features adjustable power supply current and over-temperature and over-current protection.

Specifications:

• Supply voltage: 12V - 24V
• Single coil DC current: 1.5A
• Maximum instantaneous current in the coil: 2.5A
• Logic supply voltage: 2.5V - 5.25V
• Resolution: 1, 1/2, 1/4, 1/8, 1/16 and 1/32 steps

Features:

• The module has a simple step and direction control interface.
• It can operate in six modes: full step, half step, 1/4 step, 1/8 step, 1/16 step, and 1/32 step.
• It provides control of the maximum motor current with a potentiometer, which allows the use of higher than the rated supply voltage for motors.
• Motors can be powered from 12V to 24V.
• Current consumption up to 2.5A (1.5A without external cooling).
• Thanks to the integrated voltage regulator, the user does not need to supply additional power to the logic part.
• The DRV8824 works with systems with logic voltages of 3.3V and 5V.
• The uncovered ground field at the bottom allows for soldering of cooling elements.
• The module is compatible with the A4988 controller-based system in terms of size and pins.
