3D Printer Mainboard Kit RAMPS 1.4 + Mega 2560 + DRV8825 + 12864LCD + PCB Heat Bed MK2B

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 per stage no heatsink or forced airflow (nominal to 2.2 per volume sufficient additional cooling).

Features:

1. Simple steps and direction control interfaceStep
2. Six different resolutions: full step, half step, 1/4-step1 / 8-step1/ 16-step, 1/32-step
3.CAN interfaces directly with 3.3 V and 5 V systems
4.The over-temperature thermal shutdown, overcurrent shutdown,undervoltage lockout
5. Short-to-ground short circuit load protection
6.4 Layer 2 oz copper PCB, to improve the heat dissipation
7. bottom bare welding ground following a driver IC on a printed circuit board pad
8. The module size, pins and interface matching A4988 stepper motor driver carrier in many ways
9.The adjustable current control allows you to set a potentiometer, which lets you use the stepper motor’s rated voltage or more,in order to achieve a higher maximum output current step rate
10. Intelligent chopping control automatically selects the correct current decay mode (fast or slow decay attenuation)
11. The maximum 45 V supply voltage
12. Built-in voltage regulator (the need for any external logic supply voltage)
Pay attention to the direction when installation stepper motor drives
