Inspired by the Arduino CNC Shield, offers similar functionality.
Requires a Feather-compatible microcontroller board.
– 4 slots for Pololu stepper motor drivers, 3 axis + 1 clone axis (configurable via jumpers)
– Endstops for X/Y/Z with selectable active level (high or low)
– Pins for external buttons including emergency stop
– Pins for spindle and collant control
– Configurable microstep resolution via jumpers
The beauty of this is that:
If you want to use another type of microcontroller, remove the Feather sized microcontroller board and insert the new board
If one of the motor control channels fails, swap a new one in within seconds.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
