Description

Module with a stepper motor driver based on the DRV8434A system. It allows you to supply a bipolar motor with a continuous current of up to 1.2 A per phase (up to 2 A with instantaneous current) and a voltage from 4.5 to 48 V. It can work with 1.8 V, 3.3 V and 5 V systems, which makes it that it is a universal controller for a wide range of applications.

The module uses the SPI interface and has numerous built-in functions that allow for full configuration of the controller. For the motion control itself, it can use the SPI interface or a popular control interface based on two inputs: STEP, which corresponds to one step of motor rotation, and DIR, which determines the choice of direction. The layout offers 11 resolutions from full step to 1/256 step. The maximum output current is 2 A, and the current current through the SPI interface, which protects the motor against damage. The controller has a number of built-in protections, including overheating and overvoltage.

Features

  • Supply voltage range from 4.5 V to 48 V
  • Current up to 1.2 A continuously per phase without additional cooling (temporary 2 A)
  • It can work directly with 1.8V, 3.3V and 5V systems
  • SPI interface for configuration and control
  • Optional STEP / DIR control interface
  • Step resolutions: full step with 100% current, full step with 70% current, 1/2 step, 1/4 step, 1/8 step, 1/16-steps, 1/32-steps, 1/64-steps, 1/128 steps, 1/256 steps
  • Eight customizable decay modes including dynamic decay and ripple control modes
  • Regulation of the actual current with the potentiometer, maximum is fixed at 2 A
  • Integrated blockage detection
  • Overheating thermal shutdown, overcurrent protection, open load detection, undervoltage lockout and overvoltage protection
  • Built-in EMI reduction systems
