Four Channel A4988 V3 Engraver Drive Shield Expansion Board For Arduino CNC And 3D Printer PWM Spindle Control And Direction Pins 12 To 36V DC Supports Four Stepper Motors Two IO Per Motor Two Pack

Four-Channel A4988 V3 Shield for Arduino CNC & 3D Printers
✔️ Two-pack shield drives four steppers, 12-36V DC, 2 IO per motor

This expansion board adds four drive slots for A4988/DRV8825 compatible drivers, enabling multiple motor control for Arduino-based CNC machines and 3D printers. It supports PWM spindle control, GRBL 0.9 compatibility, and runs on a 12-36V DC supply.

✅ 4-Axis support (X, Y, Z, A) or full 4th axis via D12/D13
✅ 12-36V DC operation for hobby machines
✅ Four drive slots for A4988 or DRV8825 compatible drivers
✅ 2 IO ports per motor for simple wiring
✅ End stops per axis (6 total) and coolant enable
✅ Jumpers control micro-stepping up to 1/32 (DRV8825 compatibility)
✅ PWM Spindle control and dedicated direction pins
✅ Unassembled kit; includes two shields in red

💡 What is a four-channel driver shield used for in hobby CNC and 3D printing?

It expands your control capacity and lets you run multiple motors plus spindle from a single board.
