DRV8825 Brief introduction
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 voltage)
A4988 Feature:
This product is a carrier board or breakout board for Allegro’s A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection; here are some of the driver’s key features:
+ Simple step and direction control interface
+ 5 different step resolutions: full-step, 1/2-step, 1/4-step, 1/8-step, and 1/16-step
+ Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
+ Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection
Short-to-ground and shorted-load protection
+ 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
Using the driver:
POWER connections: The driver requires a logic supply voltage (3 – 5.5 V) to be connected across the VDD and GND pins and a motor supply voltage (8 – 35 V) to be connected across VMOT and GND. It can deliver up to appr. 1 A per phase without a heat sink or forced air flow.
MOTOR connections: 4, 6, and 8-wire stepper motors can be driven by the A4988 if they are properly connected.
