Description

Specification:

CNC Expansion Board:

Version: V3.0

Size: 68 x 53 x 18mm / 2.67 x 2.08 x 0.7"

Voltage: DC 12V to 36V (only DRV8825 driver can handle up to 36V, so please consider voltage for power supply)

The V3.0 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 drive modules, which can drive

4 stepper motors, and each stepper motor only needs 2 IO ports, that is to say, 6 IO ports can manage 3 steppers The motor is more convenient to use.

PWM Spindle and direction pins,4-Axis support (X, Y, Z , A-Can duplicate X,Y,Z or do a full 4th axis with custom firmware using pins D12 and D13)

Experimental phenomenon: The stepper motor reverses one circle, pauses for 1 second, and then rotates forward one circle, and so on.

DRV8825 Stepstick Stepper Motor Driver Module:

The DRV8825 stepper motor driver carrier is a breakout board for TI's DRV8825 micro stepping bipolar stepper motor driver. The module has a pin out and interface that are nearly identical to those of our A4988 stepper motor driver board, so it can be used as a higher-performance drop-in replacement for those boards in many applications.

The DRV8825 features adjustable current limiting, overcurrent and over temperature protection, and six micro step resolutions (down to 1/32-step). It operates from 8.2 – 45 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (rated for up to 2.2 A per coil with sufficient additional cooling).

Package Include:

1 x CNC Expansion Board
