The DRV8825 stepper motor driver carrier board TI DRV8825 micro bipolar stepper motor drive is a breakthrough. The module has a pinout and interface with our A4988 stepper motor driver carrier is almost the same, so it can be used as a better performance of the pull-down menu board replacement in many applications. DRV8825 features an adjustable current limit, overcurrent and overtemperature protection, six micro-resolution (down 1/32-step). It uses 8.2 - 45 V, can provide up to about 1.5 per phase no heat sink or forced air flow (rated up to 2.2 per volume sufficient additional cooling).


Product Features

A simple steps and direction control interface
2 six different steps resolutions: full step, half step, 1/4-step1/8-step1/16-step, 1/32-step
3.CAN interface directly with 3.3 V and 5 V systems
4 Over-temperature thermal shutdown, overcurrent shutdown, undervoltage lockout
5 short to ground short circuit load protection
6.4 Layer 2 oz copper PCB, in order to improve heat dissipation
7 exposed solder ground below the bottom of the driver IC on the printed circuit board pad
8 module size, pin and interface matching A4988 stepper motor driver operators in many ways
9 adjustable current control lets you set a potentiometer, which lets you use the stepper motor's rated voltage or more, in order to achieve a higher rate of maximum output current step
10 Intelligent chopping control automatically selects the correct current decay mode (fast decay or slow decay)
11 Maximum 45 V supply voltage
12 built-in voltage regulator (the need for any external logic supply vol
