The DRV8825 is a drop-in replacement for A4988 drivers in any CNC setup. The Songhe DRV8825 ships with an aluminum heat sink included. While the A4988 can do up to 1/16 microstepping, the DRV8825 can do up to 1/32 microstepping, making the motor movement smoother. This CNC motor controller can run a 1.5 A NEMA 17 motor reasonably well and obviously any stepper motor that's smaller than that.

It can handle 1.5A current without any cooling and 2.2 A with forced air cooling and heat sinking, an upgrade from the 1A current without cooling in the A4988.

This driver can be called an upgraded version of the A4988 driver. You can always buy the original Pololu DRV8825 although you have to pay around 5 times the price for almost a negligible performance upgrade. The driver is sold as a pack of 5 pieces. This clone of the same driver by SongHe is an affordable alternative to the Pololu one with similar performance. Pololu Robotics put it on a breakout board for the first time. The DRV8825 is also a stepper IC that's manufactured by Texas Instruments. The DRV8825 Stepper Driver is yet another small CNC driver that's really popular in small CNC applications. Overall, this is a great starter stepper driver which is shockingly inexpensive. Most people set the supply at 24V to get a smooth performance from A4988. Adjusting current using the potentiometer in the A4988 Stepper Driverįor running this CNC motor controller you need a power supply voltage in the range 8V-35V. The potentiometer in the A4988 allows easy adjustment of current to match your stepper motor requirement. It is essential to run this stepper on microstepping mode to avoid resonance issues. The A4988 can do microstepping up to 1/16 with five-step modes. Note that you need one A4988 driver per stepper motor you use. This driver powers a lot of desktop CNC's and 3D printers, so it would be ideal for such an application. If you don't know which stepper motors to choose for your CNC, then this will help you- Stepper Motors for Every Type of CNC As a rule of thumb, you should ideally buy a stepper drive that has a rated current that is 1.4 times the rated current of the stepper motor. It can also run smaller NEMA 17 motors with a current rating of up to 1.5A. What does this mean in terms of stepper motors? This means the A4988 can run a NEMA 14 with current under 1A very well. However, realistically you should only expect to run up to 1A current to the stepper motor with this driver unless you want to risk frying it. With an additional large heat sink and forced airflow cooling, this driver can technically deliver up to 2A current.Īnd the BIQU A4988 does come with an aluminum heat sink. The A4988 can deliver a current of 1A to the stepper motor without a heat sink. This is likely the cheapest stepper driver option out there. This driver is sold as a pack of five with one driver costing less than a pack of gum (yes!). The BIQU stepper driver is one of the most reliable ones among those clones. Later it was cloned by many Chinese manufacturers and it currently sells for a very affordable price. This IC was first used on a breakout board and made into a practically usable stepper driver by Pololu Robotics, NV.

The code A4988 represents the model number of the stepper IC made by Texas Instruments. The Sainsmart 3018 desktop CNC uses this as the stepper driver. This stepper driver is found in a lot of budget CNC controllers and desktop CNC's. The A4988 Stepper Driver is one of the most popular small CNC stepper drivers that's on the market. Overall Best- StepperOnline DM542T Stepper Motor Driver.My best pick is the DM542T stepper driver which is a powerful yet affordable stepper driver that will suit almost any CNC application. When you buy through links on my site, I may earn an affiliate commission at no extra cost to you. To make the most of this review, you should know either the maximum current rating on your stepper motor or at what current you plan to run your motor for your torque and RPM requirement. This guide is divided into sections, where I go from stepper drivers with the lowest peak current ratings to the highest ones. Note that a stepper driver is also called a motor controller and that is interchangeably used in this guide. I wrote this guide after considering several stepper driver options and using many of them in my personal workshop. You also don't want to overbuy with an expensive stepper driver when you are running a relatively small stepper motor. Ideally, you need the driver to be capable of running your stepper motor without any excess heating or noise. If you are wondering which stepper driver to get for your DIY CNC build or to replace an existing stepper driver in your CNC, then this guide will help you.
