Big Easy Driver 2A 大功率轉譯型步進馬達驅動板

Big Easy Driver 2A 大功率轉譯型步進馬達驅動板可以驅動雙相步進電機每相最多2A。它是一個斬波器微步進驅動器，默認為16步微步進模式。它可以承受大約30V的最大電機驅動電壓，並且包括板上5V / 3.3V調節，因此只需要一個電源。儘管在1.4-1.7A /相工作的情況下，該電路板應能夠運行大多數係統，而不需要主動冷卻，但對於接近2A /相的負載，需要加裝散熱片。

特徵

• 雙極微步驅動器
• 2A / Phase Max
• 1.4-1.7A /Phase w/o Heatsink(沒有散熱片)
• 最大電機驅動電壓：30V
• 板載5V / 3.3V調節

Big Easy Driver

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.

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
