Jopto 5Pcs StepStick DRV8825 Stepper Motor Driver Carrier Reprap Module 4-layer PCB With Mini Heat Sink Compatible with 3D Printer Reprap Ramps1.4 A4988

• It is upgrade of A4988, 4-layer PCB for improved heat dissipation and decrease chip resistance. Simple step and direction control interface.
• Stepper Motor Driver (Header Pins Soldered) is a breakout board for DRV8825 microstepping bipolar stepper motor driver.
• Could be operated from 8.2V to 45V and can deliver up to approximately 1.5A per phase. It comes with 0.1"-pitch male header pins installed.
• Six different stepping resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step,1/32-step.
• DRV8825 driver board widely used in 3D printers and small CNC machines.

Features: Simple step and direction control interface. 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. 45V maximum supply voltage. Built-in regulator (no external logic voltage supply needed). Can interface directly with 3.3V and 5V 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 solderable ground pad below the driver IC on the bottom of the PCB. Module size, pinout, and interface match those of our A4988 stepper motor driver carriers in most respects. Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay). Size: 20.5 x 15 x 11.2mm Heat Sink: 8.7 x 8.7 x 5.3mm Driven Current: 2.5A Color: Purple Weight: 3g Package Content: 5 x DRV8825 Stepper Motor Driver Module 5 x Mini Heat Sink
