EPICTAC 3D Printer CNC Kit for Arduino Uno R3 with CNC Shield V3 + DRV8825 Stepper Motor Driver + Mechanical Endstop Switch Educational Electronic Hobby Kit

This 3D printer kit is a professional sensor kit. It comes with various components or sensor module for your project. All these are packaged in a portable case, easy to carry and storage.>>>>> 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.>>>>> 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: 1x CNC Shield V3 Board; 1x EPICTAC Uno R3 Board compatible with Arduino IDE; 4x DRV8825 Stepper Motor Driver with Heat Sink; 4x RAMPS Mechanical Switch Endstop; 20x 2.54mm Jumper Caps.>>>>>
