It is widely used in DIY CNC routers, 3D printers, laser engravers, and other motion control projects. This shield accepts A4988 or DRV8825 stepper motor driver modules, allowing microstepping control for smooth and accurate movement.\u003c\/p\u003e\u003ch2\u003eKey Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Arduino\u003c\/td\u003e\n\u003ctd\u003eUno (R3 layout)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMotor Drivers\u003c\/td\u003e\n\u003ctd\u003eA4988 or DRV8825 (up to 4)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAxes Supported\u003c\/td\u003e\n\u003ctd\u003eX, Y, Z, A (4 axes)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMicrostepping\u003c\/td\u003e\n\u003ctd\u003eUp to 1\/32 (dependent on driver)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Supply\u003c\/td\u003e\n\u003ctd\u003e12-36V DC (motor power)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFirmware\u003c\/td\u003e\n\u003ctd\u003eGRBL compatible\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDIY CNC router or milling machine\u003c\/li\u003e\n\u003cli\u003e3D printer with multiple extruders or dual-axis control\u003c\/li\u003e\n\u003cli\u003eLaser engraver with stepper-driven axes\u003c\/li\u003e\n\u003cli\u003eAutomated camera slider for time-lapse photography\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCompatibility\u003c\/h2\u003e\u003cp\u003eThis shield is designed to stack directly onto an Arduino Uno R3. It is compatible with GRBL firmware, which converts G-code into stepper motor pulses. It works with most A4988 and DRV8825 driver modules, supporting a wide range of NEMA 17 stepper motors. For higher current motors, consider active cooling.\u003c\/p\u003e\u003ch2\u003eWiring Notes\u003c\/h2\u003e\u003cp\u003eAlways disconnect power before inserting or removing driver modules. The motor power terminals accept 12-36V DC; ensure your power supply can handle the total current draw. The shield includes jumpers for microstepping configuration—refer to your driver’s datasheet for correct settings.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.\u003c\/p\u003e\u003cdetails\u003e\u003csummary\u003eIs this compatible with Arduino Mega?\u003c\/summary\u003e\u003cp\u003eNo, the CNC Shield V3 is designed for Arduino Uno R3 layout. For Mega, you would need a different shield or adapter.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eCan I use it without GRBL?\u003c\/summary\u003e\u003cp\u003eYes, you can write custom Arduino sketches to control the stepper motors directly using the AccelStepper library or similar. However, GRBL simplifies G-code based control.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eDoes it come with stepper drivers?\u003c\/summary\u003e\u003cp\u003eNo, this is just the shield. You will need to purchase A4988 or DRV8825 driver modules separately. We recommend at least 3 drivers for a basic 3-axis CNC setup.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
