Key Features of Arduino CNC Shield

• Plug-and-Play with Arduino Uno: Stacks directly onto the Uno header pins - no soldering, no breadboard wiring, no adapter cables required.
• 4 Independent Stepper Driver Slots: Control X, Y, and Z axes plus a 4th axis that can be configured as a clone of X or Y for dual-motor gantry systems.
• GRBL Firmware Compatible: Works seamlessly with GRBL, the industry-standard open-source CNC motion controller, accepting standard G-code commands.
• Flexible Microstepping Configuration: Onboard jumpers let you set microstepping resolution (full step through 1/16 step) independently for each axis for precision tuning.
• End Stop & Limit Switch Headers: Six dedicated pins (min and max for each axis) for homing switches and hard limits, enabling accurate machine calibration.
• Spindle & Coolant Control: Built-in PWM-capable spindle enable pin for controlling router/spindle speed and a coolant relay output for automated cooling systems.
• Wide Voltage Input (12V-36V): Separate motor power input supports a range of stepper motors and power supplies without stressing the Arduino's voltage regulator.
• Real-Time Control Pins: Dedicated header pins for Abort, Feed Hold, and Resume buttons give you physical emergency stop and pause capability.
• Universal Driver Compatibility: Accepts all pololu-format stepper drivers including A4988, DRV8825, and silent TMC2208 modules - swap drivers without changing hardware.
• Compact & Tech Depot India Design: 2-layer PCB with clean routing and proper ground planes ensures reliable signal integrity even during high-speed stepping operations.
• 100% authentic from trusted suppliers - no clones with poor solder joints or missing traces
• Ideal price-to-performance ratio for makers, students, and small workshop owners

Perfect For

• DIY CNC Router / Milling Machine: Pair with NEMA 17 stepper motors, lead screws, and a rotary tool to build a desktop CNC that cuts wood, acrylic,
• Rapid prototyping on top of an existing Arduino board without extra breadboard wiring
• Adding a specific capability (motor control, extra proto space, connectivity) to a maker project
• Classroom and workshop demonstrations of shield-based expansion
