The DRV8825 Stepper Motor Driver with Aluminum Heat Sink is a breakout board for TI’s DRV8825 microstepping 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, overcurrent, and overtemperature 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).

 

Note: We are supplying two DRV8825 Drivers as DRV8825 Stepper Motor Driver with Aluminum Heat Sink- Good Quality and DRV8825 Stepper Motor Driver with Aluminum Heat Sink- Normal Quality. The difference between them is, the good quality DRV8825 has more number of PCB layers and it features the connecting pins which are of gold plated as compared to other. (refer to above image)

 

Using the Driver

 

Features :

5. Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
6. 45 V maximum supply voltage
7. Built-in regulator (no external logic voltage supply needed)
8. Can interface directly with 3.3 V and 5 V systems

Creality Ender 3 V2

• The most notable new feature is the V2’s tempered “Carborundum” glass print bed. This is a welcome change from the detachable magnetic heated bed of the Ender 3 Pro. These beds were prone to accumulate filament residue over time, which ever so often resulted in ugly first layers.

  The glass print bed is mounted on the aluminum plate, which should improve overall material adhesion, makes the surface flatter, and lets you remove prints much more easily.

• ADDITIONAL FEATURES

• XY-axis tensioner: New to the Ender series are two knobs that will let you tighten the printer’s belts. We can’t really tell if they will bring better results or if this is something no-one needs, as most of these belts are already pre-tensioned and work without problems.
• Mean Well power supply: Like the Ender 3 Pro, the Ender 3 V2 is equipped with a Mean Well power supply.
• Manual filament feeding: Creality added a rotary knob on the Bowden feeding mechanism so you can load the filament by hand if you want to do so.
• Toolbox: Embedded in the base you’ll find a little compartment for storing nozzles, needles, pliers and other tools. We already love this one.
• Resume after a power outage: This perk was made popular by the Prusa i3 MK3 3D printer. Outages or disconnections should be no problem for Ender 3 V2 because it can fully recover and resume the print when it’s back up

The A4988 driver Stepper Motor Driver is a complete micro-stepping motor driver with built-in converter, easy to operate. It operates from 8 V to 35 V and can deliver up to approximately 1 A per phase without a heat sink or forced air flow (it is rated for 2 A per coil with sufficient additional cooling).

A4988 driver Stepper Motor Driver includes a fixed off-time current regulator, the regulator can be in slow or mixed decay mode. The converter is the key to the easy implementation of the A4988.

There are no phase sequence tables, the high-frequency control interface programming etc. The application of A4988 interface is very suitable for a complex microprocessor is not available or overload. In the stepping operation, the chopping control in the A4988 automatically selects the current decay mode (slow or mixed). The mix decay current control scheme can reduce the audible motor noise, increased step accuracy, and reduced power consumption.

Provide internal synchronous rectification control circuitry, in order to improve the pulse width modulation (PWM) power consumption during operation.

Internal circuit protection includes thermal shutdown with hysteresis, under-voltage lockout (UVLO) and crossover current protection. Don’t need special power-up sequencing. A4988 uses surface mount QFN package (ES), the size is 5 mm × 5 mm, nominal overall package height is 0.90 mm, with an exposed thermal pad to enhance the heat dissipation function.

Note: The difference between product “A4988 driver Stepper Motor Driver- Normal Quality” and “A4988 driver Stepper Motor Driver- Good Quality”  is, The good quality A4988 has more number of PCB layers and it features the connecting pins which are of gold plated as compared to other.
