Stepper motor driver module based on the DRV8434S chip from Texas Instruments. It is powered with a voltage in the range from 4.5 V to 48 V. It offers a wide range of step resolution - from full to 1/256 step. The SPI interface is used to adjust the current, step mode, decay mode and stop detection. This version has the maximum current limit fixed at 2 A and the SPI can be used to set the actual current limit to any of 16 equally spaced values from 125 mA to 2 A.

Main features:
  • Single bipolar stepper motor control
  • SPI interface
  • Ability to work in eleven modes: full step with 100% current, full step with 70% current, part 1/2-, 1/4-, 1/8-, 1/16-, 1/32-, 1/64-, 1/128-, 1/256-step
  • Supply voltage range from 4.5 V to 48 V
  • Current consumption up to 2 A per coil (1.2 A continuous)
  • Protection against overheating, short circuits and exceeding the maximum current
  • Uncovered mass field from the bottom for soldering cooling elements
Specification:
