DRV8825 Stepper Motor Driver Module

The DRV8825 Module A stroke engine driver includes an auxiliary board TI DRV8825 for launching microstrip dipole stator motors. The module has an output and interface pin which is roughly equal to the A4988's Aperture Stream Driver, which can be the highest-level replacement function for this win-win in many projects. The features of this module include setting the flow range, protecting against excess flow and excessive temperature rise, and also has 6 microspaces with a resolution of up to 1/32 steps. This module works at a voltage of 8.2 to 45 volts and can flow up to 2.5A in any phase without any fan-socket and fan current (with effective cooling up to 2.2A). This module is fully compatible with Ardino's boards.
