Fit many occasions: The stepstick driver board is suitable for drvs, motors, radiators, heat sinks, etc.
Quick installation: The stepper driver is easy to install and disassemble, which can save your time and energy.
Stepper motor driver DRV8825 with Micro-stepping capability. The module has a pinout that is identical to A4988 driver, yet it affoards better performance. Both drivers are compatible with the RAMPS shield for 3D printers and CNC.
The DRV8825 features adjustable current limiting, overcurrent, and overtemperature protection, and six microstep resolutions (down to 1/32-step). It can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (it is rated for 2.5 A per coil with sufficient additional cooling).
The driver requires a logic supply voltage (3 - 5.5 V) to be connected across the VDD and GND pins and a motor supply voltage (8 - 45 V) to be connected across VMOT and GND. The logic voltage can be supplied from an external source, such as that powering the logic of the rest of the system
Feature
4988 Features and Advantages
