Description

PCB supporting the Arduino Nano.

Provides connects for four A4988 stepper motor drivers, two PWM controlled mosfets, two termistor sensors, three limit switches, probe, and the appropriate buttons.

To be used with Teacup for 3D printing and grbl for CNC machining, both being configured to use the same pins. One PWM channel doubles as spindle control for CNC and hotend heater control for 3D printing
