Description

CNC Shield Board: 1>PWM Spindle and direction pins 2>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) 3>2 x End stops for each axis (6 in total) 4>Coolant enable 5>Uses removable A4988 or DRV8825 compatible stepper drivers 6>Compact design 7>Stepper Motors can be connected with 4 pin molex connectors or soldered in place 8>Please note that this is an unassembled kit and Basic soldering skills are needed A4988 Stepper Motor Driver: 1>Low RDS (On) Output 2>Automatic current decay mode detection / selection 3>Mix with slow current decay modes 4>Synchronous rectification for low power dissipation 5>Internal UVLO 6>Crossover-current protection 7>3.3 and 5 V compatible logic supply 8>Thermal shutdown circuitry 9>Ground fault protection 10>Load short-circuit protection 11>Five selectable step modes: full, 1/2, 1/4, 1/8 and 1/16 UNO R3 Board for Arduino: 1>MCU: ATmega328 2>USB interface: ATmega16U2 3>Operating voltage: 5V 4>Digital I/O pins: 14 (including 6 with PWM capability) 5>Analog input pins: 6 6>I-I/O pin output current: 40mA max 7>3.3V output current: 150mA max 8>Flash memory: 32kB (0.5kB used by bootloader- included) 9>Static RAM (SRAM): 2kB 10>EEPROM: 1kB 11>Clock speed: 16MHz LCD 2004 Smart Controller Easy connect it to your Ramps board using the "smart adapter" included. After connecting this panel to your Ramps you don't need your pc any more, the Smart Controller supplies power for your SD card. Further more actions like calibration, axes movements can be done by adjusting the rotary encoder on the Smart Control panel.

Features

• 3D Printer Accessories Set meets most needs. Including CNC Shield V3.0, UNO R3 Board, A4988 StepStick Stepper Motor Module.
• The 3D printer stepper motor shield V3 can be used as driver expansion board for engraving machines and 3D printers.
• It has in total 4 channel slots for A4988 stepper motor driver modules for driving 4 channel of stepper motors.
• Each channel of stepper motor only needs 2 IO ports, which means 8 IO ports is sufficient to manage 3 stepper motors.
• This shield can make quick work for managing stepper motors in your project.
