Description:
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.
由Brian Schmalz設計的 Big Easy Driver是一款步進電機驅動板，適用於最大 2A/相的雙極步進電機。它基於 Allegro A4988 步進驅動器芯片。它是流行的 Easy Driver 板的下一個版本。
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.
每個 Big Easy Driver 最多可以驅動雙極步進電機的每相最大 2A。它是一個斬波器微步驅動器，默認為 16 步微步模式。它可以承受大約 30V 的最大電機驅動電壓，並且包括板載 5V/3.3V 調節，因此只需要一個電源。儘管該板在 1.4-1.7A/相下運行時應該能夠在沒有主動冷卻的情況下運行大多數係統，但接近 2A/相的負載需要散熱器。您可以在下面的相關項目中找到推薦的散熱器。
