(More generally, rewiring anything while it is powered is asking for trouble).Color: blue + red Material: metal + PC Package Contents 1 x CNC Shield Board 4 x A4988 Stepper Motor Driver Review: saved my project - Probably the desertcart purchase of my life. I struggled so hard to try to get my step motor to work with my arduino uno R3 setup until I bought this, it does all the work. Thank you!! Be careful setting up the A4988, I accidentally put in backwards and it burnt Review: works - I use as a stepper motor tester/spare part.... ## Features - MAIN FUNCTION: The extension board can be used for engraving machine or 3D printer driver - PWM SPINDLE AND DIRECTION PIN: PWM spindle and direction pin, 4 shaft support (X, Y, Z, A - you can copy X, Y, Z or use pin D12 and D13 customize firmware perform complete shaft 4) - A4988 Stepper Motor Driver Board is a breakout board for Allegro's A4988 DMOS Micro stepping Driver with Translator and Overcurrent Protection; - Package Contents: 1 x CNC Shield Board 4 x A4988 Stepper Motor Driver - 5.CNC Shield Expansion Board V3.0 + A4988 Stepper Motor Driver with Heatsink for Arduino Kits K75 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07TT3C3HB | | Best Sellers Rank | #46,678 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #5 in 3D Printer Interface & Driver Modules | | Brand | ACEIRMC | | Brand Name | ACEIRMC | | Color | Kits | | Customer Reviews | 4.4 out of 5 stars 136 Reviews | | Display Type | Digital | | Manufacturer | Organizer | | Material | Metal | | Material Type | Metal | | Operating Temperature | 20 Degrees Celsius | | Part Number | 10536 | | Smart Home Compatibility | Not Smart Home Compatible | | UPC | 701715426405 | | Unit Count | 5.0 Count | ## Product Details - **Brand:** ACEIRMC - **Color:** Kits - **Display Type:** Digital - **Material:** Metal - **Operating Temperature:** 20 Degrees Celsius ## Images ![ACEIRMC 3D Printer CNC Shield V3 Engraver Expansion Board with 4X A4988 Driver Module and 4 x Radiator (Kits) - Image 1](https://m.media-amazon.com/images/I/81HE+hm8foL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ saved my project *by J***M on March 5, 2026* Probably the Amazon purchase of my life. I struggled so hard to try to get my step motor to work with my arduino uno R3 setup until I bought this, it does all the work. Thank you!! Be careful setting up the A4988, I accidentally put in backwards and it burnt ### ⭐⭐⭐⭐⭐ works *by M***. on March 10, 2026* I use as a stepper motor tester/spare part.... ### ⭐⭐⭐⭐ Cheapo clone of quite reasonable quality *by C***T on January 25, 2020* If you need a quick gcode setup, it's hard to beat these inexpensive Arduino GRBL setups. They are nowhere near the real one in quality, so if you're looking for excellence apply your search engine skills. If you're only looking for good-enough functionality, then this one works just fine. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/144753875-aceirmc-3d-printer-cnc-shield-v3-engraver-expansion-board-4x](https://www.desertcart.hk/products/144753875-aceirmc-3d-printer-cnc-shield-v3-engraver-expansion-board-4x) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-07-12*
