Features:
This DRV8825 Stepper Motor Driver Module is an upgrade of A4988. Use for replacing the A4988 to upgrade your 3D printer.
Highest support 32 subdivision.
Can interface directly with 3.3V and 5V systems.
4-layer, 2 oz copper PCB for improved heat dissipation.
Small chip resistance, with low heat and good heat radiation feature.
Built-in regulator (no external logic voltage supply needed).
Adjustable current control lets you set the maximum current output with a potentiometer, you can use a voltage that is higher than the stepper motor’s rated voltage to achieve higher step rates.
Intelligent chopping control automatically selects the correct current decay mode (fast decay or slow decay).
Overheating closed circuit, under voltage lockout, cross current protection.
Grounding short circuit protection and load short circuit protection.
Exposed solderable ground pad below the driver IC on the bottom of the PCB.
Module size, pinout, and interface match those A4988 stepper motor driver carriers in most respects.
