3D Printer CNC Kit with Tutorial for Arduino

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. This is the latest version of the expansion board, which can ...

Description

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

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)
