Arduino CNC Shield for Stepper Motor
- Arduino UNO shield form factor, compatible with Arduino UNO.
- GRBL v1.1 compatible. (Open source firmware that runs on an Arduino UNO that turns G-code commands into stepper signals)
- Uses removable A4988 compatible stepper drivers (Not Included)
- PWM Spindle and direction pins
- 4-Axis support (X, Y, Z , A-Can duplicate X,Y,Z or do a full 4th axis with custom firmware using pins A4 and A3)
- 2 x End stops for each axis (6 in total) + one Probe
- Coolant enable output
- Jumpers to set the Micro-Stepping for the stepper drivers.
- Stepper Motors can be connected with 4 pin connectors or soldered in place.
- Runs on 12-35V DC. (Depending on Stepper driver
L293D Arduino Motor Driver Shield
- L293D is a monolithic integrated, high voltage, high current, 4-channel driver.
- Can drive 4 DC motors or 2 stepper motors or 2 Servo.
- Up to 4 bi-directional DC motors with individual 8-bit speed selection.
- Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil or interleaved stepping.
- 4 H-Bridges: per bridge provides 0.6A (1.2A peak current) with thermal protection, can run motors on 4.5V to 10V DC.
- Pull down resistors keep motors disabled during power-up.
- reset button.
