3D Printer / CNC Control Shield

This CNC shield V3 is used as a driving shield for engraving machines, fully compatible with UNO R3. So you just need to stack it onto the UNO R3 control board.It has a total of 4-way pin slots for stepper motor drive modules to drive 4-channel stepper motors.Each stepper motor only needs 2 IO ports, so 8 IO ports are enough to manage 4 stepper motors, very easy to use. This shield can make quick work for managing stepper motors in your project Features: Uses removable Pololu A4988 compatible stepper drivers. (A4988, DRV8825 and others) (Not Included) Jumpers to set the Micro-Stepping for the stepper drivers. (Some drivers like the DRV8825 can do up to 1/32 micro-stepping ) Compact design. Stepper Motors can be connected with 4 pin molex connectors or soldered in place. Runs on 12-36V DC. (At the moment only the Pololu DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the board.) GRBL 0.9 compatible. (Open source firmware that runs on an Ardui
