The Big Easy Driver, designed by Brian Schmalz, 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.
Each 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 is required for loads approaching 2A/phase. You can find the recommended heatsink in the related items below.
Note: This product is a collaboration with Brian Schmalz. A portion of each sales goes back to him for product support and continued development.
Features:
- Bi-polar Microstepping Driver
- 2A/Phase Max
- 1.4-1.7A/Phase w/o Heatsink
- Max Motor Drive Voltage: 30V
- On-board 5V/3.3V Regulation

大易驅動，設計由布萊恩SCHMALZ ，是雙極步進電機長達最大2A /相步進電機驅動板。它是基於快板A4988步進驅動器芯片。這是流行的簡易驅動板的下一個版本。
每個大易驅動器可以驅動高達每一個雙極步進電機相2A的最大值。這是一個斬波微步進驅動器，默認為16步微模式。它可以採取的30V左右的最大電機驅動電壓，包括板載5V / 3.3V調節，所以只有一個電源是必要的。雖然這款主板應該能夠在不主動散熱，而在1.4-1.7A /相位操作運行大多數系統中， 散熱器需要接近2A /相負載。您可以在下面的相關項目推薦的散熱器。
注：本產品是與布賴恩SCHMALZ協作。每一個銷售的部分可以追溯到他的產品支持和持續發展。
特徵：
- 雙極微步進驅動器
- 2A /相最大
- 1.4-1.7A /相位W / O型散熱器
- 最大馬達驅動電壓：30V
- 板載5V / 3.3V調節
