CNC Shield Board: Latest Arduino CNC Shield Version 3.0 GRBL 0.9 compatible
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)
2 x End stops for each axis (6 in total)
Coolant enable
Compatible with A4988 or DRV8825 stepper driver
Operating voltage: 5V
Digital I/O pins: 14 (including 6 with PWM capability)
I-I/O pin output current: 40mA max
3.3V output current: 150mA max
Flash memory: 32 kB (0.5kB used by bootloader - included)
Static RAM (SRAM): 2 kB
EEPROM: 1 kB
Clock speed: 16MHz
A4988 Stepper Motor Driver Board is a breakout board for Allegro's A4988 DMOS Micro-stepping Driver with Translator and Overcurrent Protection;
Low RDS (On) Output
Automatic current decay e detection / selection
Mix with slow current decay es
Synchronous rectification for low power dissipation
Internal UVLO
Crossover-current protection
3.3 and 5 V compatible logic supply
Thermal shutdown circuitry
Ground fault protection
Load short-circuit protection
Five selectable step es: 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. (More generally, rewiring anything while it is powered is asking for trouble).
Color: blue + red
Material: metal + PC
Package Contents:
1 x CNC Shield Board
1 x UNO R3 Board for Arduino
4 x A4988 Stepper Motor Driver
4 x Heat Sink
Only the above package content, other products are not included.
Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
