The DRV8825 Stepper Motor Driver Modules are the upgraded version of A4988 Driver motors, supply up to 2.5 A peak. Suitable for 3D printers and small CNC machines.
Simple step and direction control interface, provides 6 optional step resolutions: 1/32-step, 1/16-step, 1/8-step, 1/4-step, half-step & full-step.
DRV8825 stepper motor driver module has 4-layer PCB, better heat dissipation.
Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates.
The DRV8825 has adjustable current limiting, overcurrent and overtemperature protection.
