Hands On CNC Shield Expansion Board V3.0 With Four DRV8825 Stepper Driver Modules And Heatsinks For Engravers And 3D Printers RAMPS 1.4 Compatible Supports Six Step Resolutions And Adjustable Current Limit For Smooth Accurate Motion

CNC Shield V3.0 Kit: four DRV8825 drivers and heatsinks
✔️ Pack includes 1 CNC Shield V3.0, 4 DRV8825 drivers, 4 heatsinks

The CNC Shield V3.0 expansion board is a compact drive interface designed for engraving machines and 3D printers. It provides four motor channels, letting you run X, Y, Z, and an optional A axis with compatible firmware. Dimensions: 68 x 53 x 18 mm (2.67 x 2.08 x 0.70 in).

Ready-to-use CNC shield kit for stackable drive expansion, compatible with RAMPS 1.4 style setups and GRBL controllers. Includes four DRV8825 driver modules for four motor channels, plus heat sinks for better cooling during high-speed moves.

✅ Four motor drive slots on a single board to run up to four stepper motors
✅ DRV8825 drivers with six microstep options and adjustable current limit
✅ Built-in over-temperature protection, over-current protection, and under-voltage lockout
✅ 12-36 V DC supply support (DRV8825 max 36 V) with a 4-layer copper PCB for cooling
✅ 4-axis support (X, Y, Z, A) via D12/D13 pins for custom firmware

💡 What is a CNC shield expansion board used for in hobby CNC and 3D printer builds?

It’s handy for adding drive channels and simplifying wiring for multiple steppers.
