Aoicrie 5pcs DRV8825 Stepper Motor Driver Module with Heat Sink for 3D Printer Rrerap Ramps 1.4 A4988 StepStick

Product description The DRV8825 stepper motor driver carrier is a breakout board for DRV8825 microstepping bipolar stepper motor driver. The module has a pinout and interface that are nearly identical to those of our A4988 stepper motor driver board, so it can be used as a higher-performance drop-in replacement for those boards in many applications. The DRV8825 features adjustable current limiting, overcurrent and overtemperature protection, and six microstep resolutions (down to 1/32-step). It operates from 8.2 ¨C 45 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (rated for up to 2.2 A per coil with sufficient additional cooling).
Features: – Simple step and direction control interface – Can interface directly with 3.3 V and 5 V systems – Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout – Short-to-ground and shorted-load protection – 4-layer, 2 oz copper PCB for improved heat dissipation – Exposed solder-able ground pad below the driver IC on the bottom of the PCB – Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16- step, and 1/32-step – 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 – Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay) – 45 V maximum supply voltage – Built-in regulator (no external logic voltage supply needed) – Module size, pinout, and interface match those of our A4988 stepper motor drivers
Package includes: 5 x DRV8825 Stepper Motor Driver Module 5 x Heat Sink
