Description Attachments

The Big Easy Driver is a highly versatile stepper motor driver board, crafted by Brian Schmalz, that's perfect for bi-polar stepper motors with a maximum of 2A per phase. It operates based on the Allegro A4988 stepper driver chip and is an advanced version of the widely used Easy Driver board.

The Big Easy Driver is capable of driving up to a maximum of 2A per phase of a bi-polar stepper motor. This chopper microstepping driver defaults to a 16 step microstepping mode. It can handle a maximum motor drive voltage of approximately 30V, and it features on-board 5V/3.3V regulation, meaning only a single supply is necessary. For systems operating at 1.4-1.7A per phase, active cooling isn't typically required. However, for loads nearing 2A per phase, a heatsink is recommended. The suggested heatsink can be found in the related items section.

This product is a result of a collaboration with Brian Schmalz. A portion of the sales proceeds goes back to him, contributing to the product's support and ongoing development.
