Description

The DRV8825 stepper motor driver carrier is a breakout board for TI’s DRV8825 micro-stepping bipolar stepper motor driver. The Stepper Driver 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 Arduino stepper motor controller features adjustable current limiting, over-current, and over-temperature protection, and six micro-step 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).

Features Of Drv8825 Stepper Motor Driver RAMPS Heat Sink 3D Printer Motor Driver:

• Microstep resolutions: full, 1/2, 1/4, 1/8, 1/16, and 1/32.
• 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. Hence 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)
• 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 solderable ground pad below the driver IC on the bottom of the PCB

eaders are not the only ones you need to woo with the introduction. Search engines like to “read” introductions too. Including your focus keyphrase at the start of your text is like giving search engines clues on the topic of your post. Moreover, Google sometimes uses your first paragraph to create a meta description. So you’ll do yourself a huge favor by including your focus keyphrase at the start.Ok, sounds easy enough. Just add the focus keyphrase at the start, and that’s it. Well, yes, but that is just the beginning. How you write the rest of the introduction is also vital.
