$3.20 Shipping Condition: New Location: China Description This module is blue PCB now.Please know it. The DRV8825 stepper motor driver carrier is a breakout board for TI's DRV8825 microstepping ... morebipolar 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– 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) 1）Simple step and direction control interface 2）Six different step resolutions: full-step. Half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step 3）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 4）45 V maximum supply voltage 5）Built-in regulator(no external logic voltage supply needed) 6）Can interface directly with 3.3 V and 5 V systems 7）Over-temperature thermal shutdown. Over-current shutdown, and under-voltage lockout 8）Short-to-ground and shorted-load protection 9）4-layer. 2 oz copper PCB for improved heat dissipation 10）Exposed solderable ground pad below the driver IC on the bottom of the PCB 11）Module size. Pinout, and interface match those of our A4988 stepper motor driver carriers in most respects(see the bottom of this page for more information) This product is a carrier board or breakout board for TI’s DRV8825 stepper motor driver; we therefore recommend careful reading of the DRV8825 datasheet(1MB pdf) before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 2.2 A output current per coil(see the Power Dissipation Considerations section below for more information) Here are some of the driver’s key

The product can be full. Half, 1/4, 1/8 and 1/16 step mode to operate bipolar stepper motor output drive capacity of up to 35 V and ± 2 A. A4988 includes a fixed off-time current regulator. The regulator can slow or mixed decay mode. The converter is the key to the easy implementation of the A4988. In inputting one pulse on the STEP input drives the motor one microstep. No phase sequence tables, high frequency control lines, or complex interfaces to programming. A4988 interface is very suitable for complex microprocessor is unavailable or is overburdened. Micro-step operation. The chopping control in the A4988 automatically selects the current decay mode(Slow or Mixed) In the mixed decay mode, the device is initially set to fast decay in the part of the fixed off-time, then a slow decay in the rest of the downtime. Mixed-decay current control scheme results in reduced audible motor noise, increased step accuracy, and reduced power consumption. Internal synchronous rectification control circuitry to improve the pulse-width modulation(PWM) power consumption when operating. Internal circuit protection includes: thermal shutdown with hysteresis, undervoltage lockout(UVLO) and crossover current protection. Special power-Sort.
