The Arduino CNC Shield makes it easy to get your CNC projects up and running in a few hours. It uses opensource firmware on Arduino to control 4 stepper motors using 4x A4988 or DRV8825 with this shield and an Arduino you can build all kinds of robotics or CNC projects including CNC routers, laser cutters and even pick&place machines.
This is the KIT...
This is a splittable 40 pin male-female jumper wire, it is super flexible, can be transformed from 1-40 pin jumper wire. With some of these, you will no need to worry about the jumper wires you got before do not fit your project, just split it and go.
Plug the RaspiRobot Board into the GPIO port on the Raspberry Pi and it provides dual bi-directional motor controllers, two open collector outputs, two switch inputs, a pair of status LEDs and even a voltage regulator capable of powering the Pi using a battery source from 7-12VDC.
