Check the listing for details. 5PC DRV8825 Driver Stepper Motor Driver Module with Heatsink 3D Printer Supplies. Condition: New. Listed at 16.92 USD. Item Description: The DRV8825 stepper motor driver carrier is a breakout board for Texas Instruments DRV8825 micro stepping bipolar stepper motor driver. The module has a pinout and interface that are nearly identical to those of the A4988 stepper motor driver carriers, so it can be used as a higher performance drop in replacement for those boards in many applications. The DRV8825 features adjustable current limiting, over current and over temperature protection, and six microstep resolutions (down to 1/32 step). It operates from 8.2 – 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). 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. Key Features: Simple Step & Direction Control Interface Size: 1.5mmX2mm (same as 4988) Can Interface Directly With 3.3 Volt & 5 Volt Systems Six Step Resolutions: Full Step, Half Step, 1/4-Step, 1/8-Step, 1/16-Step, and 1/32-Step Short-To-Ground & Shorted-Load Protection 4 Layer, 2 oz Copper PCB For Improved Heat Dissipation Exposed Solderable Ground Pad Below Driver IC On Bottom Of PCB Over Temperature Thermal Shutdown, Over Current Shutdown & Under Voltage Lockout Module Size, Pinout Interface Match Those Of The A4988 Stepper Driver Carriers In Most Respects Built In Voltage Regulator (no external logic voltage supply needed) Maximum 45 V Supply Voltage Product Details: 5 x DRV8825 Stepper Motor Driver 5 x Aluminium Heatsink
