KeeYees Professional 3D Printer CNC Kit with Tutorial for Arduino, CNC Shield V3 w/Jumpers + UNO R3 Board + 4Pcs RAMPS 1.4 Mechanical Switch Endstop & DRV8825 GRBL Stepper Motor Driver Heat Sink

CNC Expansion Board:
-GRBL 0.9 compatible
-Runs on 12-36V DC
-4-Axis support: X, Y, Z
-It can drive 4 stepper motors, and each stepper motor only needs 2 IO ports.
That is to say, 6 IO ports can manage 3 stepper motors very well,
which is very convenient to use.

KeeYees UNO R3 Board:
-Microcontroller: ATmega328P
-Chip: ATmega16U2 
-Operating Voltage: 5V
-Input Voltage (recommended):7-12V
-Input Voltage (limit):6-20V
-Flash Memory: 32 KB of which 0.5 KB used by bootloader
-Digital I/O Pins: 14 Digital I/O Pins (6 PWM outputs)
-Analog Input Pins: 6 DC Current per I/O Pin 40 mA DC Current for 3.3V Pin 50 mA
-SRAM: 2 KB
-EEPROM: 1 KB
-Clock Speed: 16 MHz
Tips: Find more information about Arduino UNO R3 with the Expansion Board IO Port with our tutorial.

DRV8825 Stepper Motor Driver:
-Applied for driving stepper motors up to 8.2V-45V 2.5A
-4-layer PCB board (better heat dissipation)
-6 different step resolutions:
full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step

Mechanical Switch Endstop:
-Length of Cable: 70 cm
-Red line — VCC (ramps of +)
-Black wire — GND (ramps of -)
-Green Line — SIGNAL (ramps in s)

Package Contents:
1 x CNC Shield Board
1 x KeeYees UNO R3 Board
4 x DRV8825 Stepper Motor Driver with Heat Sink
4 x RAMPS Mechanical Switch Endshop
20 x 2.54mm Black Jumper Caps

Product Features

  • 【KeeYees UNO R3 Board】 KeeYees UNO R3 Board uses the same ATmega328 and ATMega16U2 as official Uno R3 and 100% compatible with the official version. It comes with free 1.5m USB cable for convenient connection.
  • 【CNC Expansion Board with Free 20pcs Jumpers】This is the latest version of the expansion board, which can be used for engraving machines and 3D printers. It can drive 4 A4988/DRV8825 stepper motors. The jumper caps are necessary for CNC setups. You do not need to purchase this part extra.
  • 【DRV8825 Stepper Motor Driver w/ Heat Sink】DRV8825 is upgrade of A4988! It is a must-have module for 3D printers, CNCs and engraving machines. The 4-layer PCB board has better heat dissipation performance. 
  • 【Mechanical Switch Endstop】It uses a 22AWG wire that can withstand a current of 2A and a voltage of 300V. Better quality than traditional copper wire. It can reach the insulation temperature of 80℃. It is not easy to break, and very convenient to plug and remove.
  • 【Reliable technical support】If you don’t have a CD drive, please visit our website( www.keeyees.com ) to get relevant information or can contact us on Amazon, we will send PDF Document to you.
