DRV8825 Stepper Motor Drive Module 2.5A 8.2V~45V Suitable for Module Stepper Motor Required by 3D Printer cnc Engraving Machine
This module isPCB now, please keep it in mind. The DRV8825 Stepper Motor Controller Carrier is a break board for TI's DRV8825 bipolar stepper motor controller. The module has a pinout and interface that are almost identical to those on our A4988 stepper motor controller board, so it can be used as a high-performance replacement for those boards in many applications.The DRV8825 features adjustable current limitation, overcurrent and overheating protection, and six microstep resolutions (up to 1/32 steps). It operates from 8.2-45 V and can deliver up to about 1.5 A per phase without a heat sink or forced airflow (rated for up to 2.2 a per coil with sufficient additional cooling).1 step and direction control interface Simple2seisdifferent step resolutions: full step, half step, step 1/4, step 1/8, step 1/16 and step 1/323Adjustable current control allows you to set the maximum current output With a potentiometer, which allows you to use voltages above the rated voltage of your stepper motor to achieve higher rates of stepMaximumsupply voltage of 445 V5built-in regulators (no external logical voltage supply needed)6Can interface directly with 3.3 V and 5 V7systems thermal shutdown due to overheating, overcurrent shutdown and low voltageblocking 8.

This stepper motor controller allows you to control a bipolar stepper motor A up to 2.2 A output current per coil (see the energy dissipation ratios section below for more information). Here are some of the main features of the conductor:SimpleStep and Direction Control InterfaceShese different step resolutions: full step, half step, step 1/4, step 1/8, step 1/16 and step 1/32Adjustablecurrent control allows you to set the maximum current output With a potentiometer, which allows you to use voltages above the rated voltage of your stepper motor for achieve higher passratesIntelligent cutting control that automatically selects the correct current drop mode (fast drop or slow drop)Maximum supply voltage of 45 VBuilt-in regulator (no external logical voltage source needed)Can be connected directly with 3.3 V and 5 VsystemsThermal shutdown due to overheating, overcurrent shutdown and low voltage blocking.Short Circuit and Short CircuitProtection4-layer, 2 oz copperPCB for better heatdissipationExt weldable earth pad under the IC controller at the bottom of the PCBThemodule size, design and interface match those of our A4988 stepper motor controller carriers in most respects (see bottom of This page for more information)We also have a DRV8824 stepper motor controller carrier that can serve as a direct substitute for the DRV8825 carrier when using lower current stepper motors. The DRV8824 can only deliver up to 0.75 A per coil without a heat sink (1.2 to maximum with adequate cooling). But it has larger current sensing resistors that allow for better microstep performance than the DRV8825 carrier at low currents. The only way to tell our carrier DRV8824 apart from the DRV8825 carrier is by the markings on the driver's IC; If you have a mixture of the two, you may consider marking them (there is a blank square on the bottom silk screen that you can use for this). For low-voltage applications, consider our pin-compatible DRV8834 carrier, which works with motor supply voltages as low as 2.5V.This product ships with all surface mount components, including the DRV8825 IC controller, installed as shown in the product image.
