Opencircuit CNC Shield v4 Arduino Nano

The CNC Shield v4 is made for the control of 3D printers, milling and engraving machines. This version of the shield has 1 motor driver less than its predecessor, but is more compact and has room for an Arduino Nano. This board has 3 sockets for the installation of stepper motor drivers such as the A4988. Only 2 channels per motor are required to control this motor. There is also a connection for 2 end-stop switches per motor.Properties- GRBL compatible- 3 connections, XYZ- 2 end stops per axle (6 in total)- Spindle on / off and direction- Adjustable for Micro-Stepping with jumpers (not included)- 12-36V DC. (The motor driver must be able to handle this, note this during installation)- Delivered without stepper drivers
