1pc 3D Printer CNC Shield V3 Engraver Expansion Board + 4pcs A4988 Driver Module

Features:

• The expansion board can be used as engraving machine, 3D printer and other drive expansion board.
• Compatible with GRBL 0.8. Open source firmware running on for Arduino UNO that converts G code commands into stepped signals.
• PWM spindle and direction pins, support 4-axis (X, Y, Z, A - you can copy X, Y, Z or use the pin of D12 and D13 to custom firmware to perform the complete axis 4).
• Compact structure, stepper motors can be connected to 4 pin connectors or soldered.
• This is a set of disassembled parts and you need basic soldering techniques to solder them together.
