This expansion board, as drive expansion board, can be used for engraving machines and 3D printers. It totally has four slots and can drive 4 A4988 stepper motors, and each stepper motor only needs two IO ports. That is, 6 IO ports can be well managed three stepper motors. A4988 is a complete micro-stepping motor driver with built-in translator for easy operation.
Features:
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).
A4988 driver expansion board can be used for engraving machines and 3D printers.
Specifications:
CNC Shield Board:
* PWM Spindle and direction pins
* 2 x End stops for each axis (6 in total)
* Coolant enable
* Uses removable A4988 compatible stepper drivers
* Compact design
* Stepper Motors can be connected with 4 pin connectors or soldered in place
* Runs on DC 12-36V (At the moment only the DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the board.)
* Please note that this is an unassembled kit and Basic soldering skills are needed
A4988 Stepper Motor Driver:
* Low RDS (On) Output
* Automatic current decay mode detection / selection
* Mix with slow current decay modes
* Synchronous rectification for low power dissipation
* Internal UVLO
* Crossover-current protection
* 3.3V and 5V compatible logic supply
* Thermal shutdown circuitry
* Ground fault protection
* Load short-circuit protection
* Five selectable step modes: full, 1/2, 1/4, 1/8 and 1/16
* Warning: Connecting or disconnecting a stepper motor while the driver is powered can destroy the driver.
Package List:
1 * CNC Shield V3 Board
4 * A4988 Driver Module
4 * Heat Sink
