DRV8834 stepper motor driver, low voltage 10.8V 2A, Pololu 2134

Все о продукте

The stepper motor controller based on the DRV8834 system allows you to control a motor with a current consumption of up to 1.5 A (instantaneous up to 2 A) per coil with a voltage of 2.5 V to 10.8 V. It has six operating modes: full step, 1/2, 1/4, 1/8, 1/16 and 1/32 step.

Main features:

• The module has a simple interface for controlling steps and direction
• It can operate in six modes: full, half, 1/4, 1/8, 1/16 and 1/32 step
• This allows you to control the maximum motor current using a potentiometer, which allows you to use a supply voltage higher than the rated motor voltage, so you can get a higher step speed
• Motors can be powered from 2.5 V to 10.8 V
• Current consumption up to 2 A per coil (continuous 1.5 A)
• Thanks to the integrated voltage regulator, the user does not need to supply additional power to the logic part
• The DRV8834 works with systems with both 3.3V and 5V logic voltages
• Has protection against overcurrent, temperature, short circuit and undervoltage lockout system
• To increase the heat-retaining surface, the board is manufactured using four-layer technology with a thicker copper cover
• The open area on the underside allows for soldering of cooling elements
• The module is compatible with the A4988 controller in terms of size and output.
