{"product_id":"pl4-rob-12859","title":"Big Easy Driver","description":"\u003cp\u003eThe Big Easy Driver, designed by [Brian Schmalz](http:\/\/www.schmalzhaus.com\/), is a stepper motor driver board for bi-polar stepper motors up to a max 2A\/phase. It is based on the Allegro A4988 stepper driver chip. It's the next version of the popular Easy Driver board.\u003c\/p\u003e\n\n \u003cp\u003eEach Big Easy Driver can drive up to a max of 2A per phase of a bi-polar stepper motor. It is a chopper microstepping driver which defaults to 16 step microstepping mode. It can take a maximum motor drive voltage of around 30V, and includes on-board 5V\/3.3V regulation, so only one supply is necessary. Although this board should be able to run most systems without active cooling while operating at 1.4-1.7A\/phase, a [heatsink](https:\/\/www.sparkfun.com\/products\/11510) is required for loads approaching 2A\/phase. You can find the recommended heatsink in the related items below.\u003c\/p\u003e\n\n\u003cp\u003e**Note:** This product is a collaboration with Brian Schmalz.
