Introduction The DRV8825 stepper motor driver carrier board TI DRV8825 micro bipolar stepper motor drive is a breakthrough the module pinout and interface with our A4988 stepper motor driver carrier is almost the same so it may be a better performance from the pull down menu board replacement in many applications DRV8825 features an adjustable current limit overcurrent and overheating protection six micron resolution down 1 32 step the use 8 2 45 V up to 1 5 perstage no heatsink or forced airflow nominal to 2 2 per volume sufficient additional cooling Features 1 Simple steps and direction control interfaceStep2 Six different resolutions full step half step 1 4 step1 8 step1 16 step 1 32 step3 CAN interfaces directly with 3 3 V and 5 V systems4 The over temperature thermal shutdown overcurrent shutdown undervoltage lockout5 Short to ground short circuit load protection6 4 Layer 2 oz copper PCB to improve the heat dissipation7 bottom bare welding ground following a driver IC on a printed circuit board pad8 The module size pins and interface matching A4988 stepper motor driver carrier in many ways9 The adjustable current control allows you to set a potentiometer which lets you use the stepper motors rated voltage or more in order to achieve a higher maximum output current step rate10 Intelligent chopping control automatically selects the correct current decay mode fast or slow decay attenuation 11 The maximum 45 V supply voltage12 Built in voltage
