In the mixed decay mode, the device is initially set to fast decay in the part of the fixed off-time, then a slow decay in the rest of the downtime. Mixed-decay current control scheme results in reduced audible motor noise, increased step accuracy, and reduced power consumption. Internal synchronous rectification control circuitry to improve the pulse-width modulation (PWM) power consumption when operating. Internal circuit protection includes: thermal shutdown with hysteresis, under-voltage lockout (UVLO) and crossover current protection. Special power-Sort. Features: -Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay). -Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection. -Automatic current decay mode detection / selection. -Internal UVLO. -Mixed with slow current decay modes. -Synchronous rectification for low power dissipation. -Crossover-current protection. -Thermal shutdown circuitry. -3.3 and 5 V compatible logic supply. -Thermal shutdown circuitry. -Ground Fault Circuit. -Load short-circuit protection. -Of five optional step mode: full, 1/2, 1/4, 1/8 and 1/16 Package Included:. 5* A4988 StepStick Stepper Motor Diver Module 5* Heat Sink ## Features - A4988 driver board widely used in 3D printers and small CNC machines. - Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step. Output drive capacity of up to 35 V and ± 2 A. - Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor's rated voltage to achieve higher step rates. - Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay) - Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection. ## Images ![GeeBat A4988 Stepstick Stepper Motor Driver Module with Heat Sink for 3D Printer Reprap CNC Machine or Robotics (Pack of 5pcs) - Image 1](https://images-na.ssl-images-amazon.com/images/I/512Vy-BNFrL.jpg) ![GeeBat A4988 Stepstick Stepper Motor Driver Module with Heat Sink for 3D Printer Reprap CNC Machine or Robotics (Pack of 5pcs) - Image 2](https://images-na.ssl-images-amazon.com/images/I/412AWwvTBiL.jpg) ![GeeBat A4988 Stepstick Stepper Motor Driver Module with Heat Sink for 3D Printer Reprap CNC Machine or Robotics (Pack of 5pcs) - Image 3](https://images-na.ssl-images-amazon.com/images/I/41pSTkMurWL.jpg) ![GeeBat A4988 Stepstick Stepper Motor Driver Module with Heat Sink for 3D Printer Reprap CNC Machine or Robotics (Pack of 5pcs) - Image 4](https://images-na.ssl-images-amazon.com/images/I/41XhSKCa7nL.jpg) ![GeeBat A4988 Stepstick Stepper Motor Driver Module with Heat Sink for 3D Printer Reprap CNC Machine or Robotics (Pack of 5pcs) - Image 5](https://images-na.ssl-images-amazon.com/images/I/31IYl7-3CUL.jpg) --- ## 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.kg/products/39171970-geebat-a4988-stepstick-stepper-motor-driver-module-with-heat-sink](https://www.desertcart.kg/products/39171970-geebat-a4988-stepstick-stepper-motor-driver-module-with-heat-sink) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-05-07*
