PRODUCT FEATURES

【Main Application】This expansion board and DRV8825 Stepper Motor Driver can be used as a drive expansion board for engraving machines, 3D printers, etc.
【CNC Shield V3 Expansion Board Feature1】There are a total of 4 slots for stepper motor drive modules, which can drive 4 routes without motors, and each stepper motor only needs 2pcs IO port.
【CNC Shield V3 Expansion Board Feature2】That is to say, 6pcs IO port can manage 3 stepping motors well, which is very convenient to use, bid farewell to the cumbersome operation of traditional stepping motors.
【DRV8825 Stepper Motor Driver Feature1】The DRV8825 stepper motor driver module has a pinout that is almost identical to the interface and the A4988 stepper motor carrier, so it can be used as a higher performance replacement in many applications.
【DRV8825 Stepper Motor Driver Feature2】DRV8825 has adjustable current limit, overcurrent and thermal protection, 6 micro resolutions (1, 1/2, 1/4, 1/8, 1/16, 1/32). It uses 8.2-45V and can provide Up to about 1.5 per phase or forced air flow (rated up to 2.2 per roll with sufficient additional cooling).

CNC GRBL Shield Board V3 Expansion Board

Product Description

The expansion board can be used as a drive expansion board for engraving machines, 3D printers, etc. There are a total of 4 slots for stepper motor modules, which can drive stepper motors, and each stepper motor only needs 2 IO ports, also That is to say, 6 IO ports can manage 3 stepping motors well, which is more convenient to use and bid farewell to the tedious operation of traditional stepping motors.

Introduction of the corresponding relationship between UNO and module IO port

UNO-------------Expansion Board

8-------------EN (stepping motor drive enable terminal, active low)
7-------------Z.DIR (direction control of Z axis)
6-------------Y.DIR (direction control of Y axis)
5-------------X.DIR (direction control of X axis)
4-------------Z.STEP (step control of Z axis)
3-------------Y.STEP (Y-axis step control)
2-------------X.STEP (step control of X axis)

Experimental Phenomenon: the stepper motor reverses one circle, pauses for one second, and then rotates forward one circle, and so on
Attention: When inserting the stepper motor, be careful not to insert it backwards.
The wiring method of the stepper motor is: 2A, 2B are a group (red, green), 1A, 1B are a group (blue, yellow).
I fusers want to change Direction, change the position of one of the groups, such as 2A and 2B exchange.

Features and advantages over A4988

Current up to: 4.5A
Supports up to: 32 subdivisions
4-layer PCB board, good heat dissipation performance
The internal resistance of the chip is smaller, the heat generation is low, and the heat dissipation performance is good.

DRV8825 Stepper Motor Driver with Heatsink

Product Description

The DRV8825 stepper motor driver module has a pinout that is almost identical to the interface and the A4988 stepper motor carrier, so it can be used as a higher performance replacement in many applications.

DRV8825 has adjustable current limit, overcurrent and thermal protection, 6 micro resolutions (1, 1/2, 1/4, 1/8, 1/16, 1/32). It uses 8.2-45V and can provide Up to about 1.5 per phase or forced air flow (rated up to 2.2 per roll with sufficient additional cooling).

Features

Simple steps and directional control interface
Six product segments: 1, 1/2, 1/4, 1/8, 1/16, 1/32
CAN interface directly with 3.3V and 5V systems
Over temperature and over current shutdown protection, under voltage lockout
Short-to-ground short-circuit load protection
4-layer 2oz copper PCB for improved heat dissipation
Exposed ground pads on the bottom of the PCB for soldering below the driver IC
Adjustable current control allows setting a potentiometer, which allows the use of a stepper motor with a voltage above the rated voltage to achieve higher step rates to output large currents
Intelligent chopper control automatically selects the correct current decay mode (fast decay and slow decay)
Stable 45V supply voltage
Built-in voltage regulator (requires any external logic supply voltage)
