DRV8825 Stepper motor driver is an upgrade of the A4988.
Includes heat sink.
Max Output Current: 2.2A
Max Input Voltage: 45V
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
Step Resolutions - Full Step, Half step, 1/4 Step, 1/8 Step, 1/16 Step and 1/32 Step.
Over temperature thermal shutdown, over current shutdown, and under-voltage lockout.
Short to ground and shorted-load protection.
