DRV8825 stepper motor driver

 Features

Advantages of DRV8825 compared to A4988:

1. Maximum current 2.5A
2. Supports up to 32 microsteps
3. 4-layer PCB, better heat dissipation performance
4. Lower chip internal resistance, less heat generation, better heat dissipation.        Product Parameters

• Drive current: 2.5A
• Microstep options: 1, 1/2, 1/4, 1/8, 1/16, 1/32
• Manufacturing process: SMT chip manufacturing, non-manual soldering, higher yield, more stable performance

Applicable Uses
