The A4988 is a complete microstepping motor driver with built-in translator for easy operation. It is designed to operate bipolar stepper motors in full-, half-, quarter-, eighth-, and sixteenth-step …

This breakout board for Allegro’s A4988 microstepping bipolar stepper motor driver features adjustable current limiting, over-current and over-temperature protection, and five different …

It features a four-layer PCB for better thermal performance, allowing the A4988 microstepping bipolar stepper motor driver to deliver approximately 20% more current than our two-layer …

The A4988 stepper motor driver carrier with voltage regulators comes with 0.1″ male header pins that can be broken into smaller strips and soldered in for use with solderless breadboards or …

This is a bulk-packaged version of our A4988 Stepper Motor Driver carrier that ships without header pins; we carry compatible 0.1″-pitch 40-pin male header strips that can be purchased …

Dec 6, 2011 · I modified the circuit with the control lines opto coupled and I added capacitors to each one 4,7 microF and 100 nF the board works properly during a while but sudenly one of …

The DRV8825 driver IC has a maximum current rating of 2.5 A per coil, but the current sense resistors further limit the maximum current to 2.2 A, and the actual current you can deliver …

Oct 5, 2021 · I am using the AccelStepper library for Arduino and an A4988 driver in order to control a Nema17 stepper motor. When I establish the stepper class instance, the stepper …

May 7, 2017 · While the A4988 driver IC has a maximum current rating of 2A per coil, the actual current you can get from it depends on how well you can keep the IC cool. On our #1183 …

Jan 12, 2014 · I want the motors to run with less noise. (This actually why I bought DRV8825 instead of A4988. I will upgrade to 1/32ustepping later.) I installed heatsinks and they will not …
