V3.0 Engraver CNC Shield+Board + A4988 Stepper Motor Driver Row Needles For UNO R3 Arduino Carving Machine Accessories

Engraver CNC Shield Board:
Version:3.0
Color:Red
Size:68 x 53 x 18 mm
Voltage:DC 12~36 V (At the moment only the DRV8825 drivers can handle up to
36V so please consider the operation voltage when powering the board.)

Feature:
1.Uses removable A4988 or DRV8825 compatible stepper drivers.
2.The extension board can be used for carving machine, 3 d printer driver expansion board
3.GRBL 0.8 compatible. (Open source firmware that runs
on an for UNO that turns G-code commands into stepper signals)
4.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)
5.Compact design. Stepper Motors can be connected with 4 pin molex connectors or soldered in place.
6.Please note that this is an unassembled kit and Basic soldering skills are needed.

A4988 Stepper Motor Driver:
Color:Red
Size(L*W*H):20 x 15 x 10 mm
Thermal shutdown circuitry:Yes
Crossover-current protection:Yes
Ground fault protection:Yes
Load short-circuit protection:Yes
Compatible logic supply: 3.3V and 5 V
Five selectable step modes: full, 1/2, 1/4, 1/8 and 1/16

Features:
1.Mix with slow current decay modes.
2.Internal UVLO and Low RDS (On) Output.
3.Automatic current decay mode detection/selection.
4.Synchronous rectification for low power dissipation.
5.Warning: Connecting or disconnecting a stepper motor while the driver is powered can destroy the driver.
