Supporting up to 4 stepper motors with efficient IO usage, it runs on 12-36V DC and is compatible with A4988 and DRV8825 drivers, enabling advanced micro-stepping control. Perfect for makers and professionals seeking customizable, open-source firmware integration and reliable motor management. ## Description GRBL 0.9 compatible. (Open source firmware that runs on an Arduino UNO that turns G-code commands into stepper signals) PWM Spindle and direction pins 4-Axis support (X, Y, Z , A-Can duplicate X,Y,Z or do a full 4th axis with custom firmware using pins D12 and D13) 2 x End stops for each axis (6 in total) Coolant enable Uses removable A4988 or DRV8825 compatible stepper drivers Jumpers to set the Micro-Stepping for the stepper drivers. (Some drivers like the DRV8825 can do up to 1/32 micro-stepping) Compact design. Stepper Motors can be connected with 4 pin molex connectors or soldered in place. Runs on 12-36V DC. (At the moment only the DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the board.) Please note that this is an unassembled kit and Basic soldering skills are needed Package List:2*V3 Engraver Shield 3D Printer CNC Expansion Board A4988 Driver Board ## Features - Each road stepper motors only need two IO ports - This expansion board as a driver expansion board, can be used for engraving machines, 3D printers. - PWM Spindle and direction pins. 4-Axis support. Runs on 12-36V DC - It is a total of four slots, can drive four A4988 stepper motor. Each road stepper motors only need two IO ports. In other words, six IO ports can be well managed three stepper motors. Very convenient to use. - Stepper motor wiring as follows: 2A, 2B is a group (red, green), 1A, 1B is a group (blue, yellow), if want to change direction, can be change the position of one group , for example 2A, 2B mutually exchanged. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01D2HL9T8 | | Best Sellers Rank | #97,672 in Computers ( See Top 100 in Computers ) #1,542 in Single-Board Computers | | Brand Name | HiLetgo | | Customer Reviews | 4.5 4.5 out of 5 stars (280) | | Item Weight | 0.07 Kilograms | | Manufacturer | HiLetgo | | Material Type | Metal | | Model | 3-01-1086 | | Model Name | A4988 | | Part Number | 3-01-1086-UK-2PCS | | Voltage | 36 Volts | ## Product Details - **Brand:** HiLetgo - **Item weight:** 0.07 Kilograms - **Material:** Metal - **Model name:** A4988 - **Voltage:** 36 Volts ## Images ![2pcs V3 Engraver Shield 3D Printer CNC Expansion Board A4988 Driver Board for Arduino - Image 1](https://m.media-amazon.com/images/I/71yyrwyKjqL.jpg) ## Questions & Answers **Q: Are 4-pin molex pin connectors a standard size for a cnc shield?** A: Yes, that's what I'm using. **Q: could I use a regular 12v dc power block or do I need to use a proper power supply?** A: Yeah, 12v power brick worked for me, at least for experimental stages, it'll need to have enough current (obviously) to run the motors. Current requirements also depends a bit on how your driver's are tuned and the motors your running. **Q: Will this be ship from the USA or other country ?** A: other country **Q: Which grbl 0.9 is this shield support?the z spindle is swapped at middle of 0.9;1.7a stepper motor is currently not working after i calib vref to 0.75** A: This seems to work just fine with the grbl .9 at github. I'm using one of these in a drawingbot I built, but my Z is a servo and not a stepper. The XY steppers work just fine.
