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
