It features a four-layer PCB for better thermal performance, allowing the A4988 microstepping bipolar stepper motor driver to deliver approximately 20% more current than our two-layer version. Like our original carrier, the Black Edition offers adjustable current limiting, overcurrent protection, and five different microstep resolutions. It operates from 8 – 35 V and can deliver up to 2 A per coil with sufficient additional cooling.\n\nA4988 stepper motor driver carrier, Black Edition, bottom view with dimensions.\n            \n\n［Overview］\n\n　　This product is a carrier board or breakout board for Allegro’s A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection; we therefore recommend careful reading of the A4988 datasheet (380k pdf) before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 2 A output current per coil (see the Power Dissipation Considerations section below for more information). \n\nHere are some of the driver’s key features：\n\n    - Simple step and direction control interface\n        \n    - Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step\n        \n    - Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates\n        \n    - Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)\n        \n    - Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection\n        \n    - Short-to-ground and shorted-load protection\n        \n    - 4-layer, 2 oz copper PCB for improved heat dissipation\n        \n    - Exposed solderable ground pad below the dr...","shipping_methods":[{"name":"郵局掛號","fee":0,"currency":"TWD"},{"name":"7-ELEVEN取貨付款","fee":0,"currency":"TWD"},{"name":"7-ELEVEN取貨不付款","fee":0,"currency":"TWD"}],"lowest_shipping_fee":null,"payment_methods":["ATM轉帳","7-ELEVEN取貨付款"],"category_id":"2092072544","category_name":"其他電腦周邊","breadcrumb":[{"id":"23336","name":"電腦、平板與周邊","url":"/tw/%E9%9B%BB%E8%85%A6%E3%80%81%E5%B9%B3%E6%9D%BF%E8%88%87%E5%91%A8%E9%82%8A-23336-category.html"},{"id":"2092072522","name":"電腦/筆電周邊","url":"/tw/%E9%9B%BB%E8%85%A6-%E7%AD%86%E9%9B%BB%E5%91%A8%E9%82%8A-2092072522-category.html"},{"id":"2092072544","name":"其他電腦周邊","url":"/tw/%E5%85%B6%E4%BB%96%E9%9B%BB%E8%85%A6%E5%91%A8%E9%82%8A-2092072544-category.html"}],"view_count":0,"watch_count":0}
