{"title":"Big Easy Driver","handle":"big-easy-driver","url":"/products/big-easy-driver","description":"The Big Easy Driver is a stepper motor driver board for bipolar stepper motors up to 2 A per phase, based on the Allegro A4988 driver chip. Designed by Brian Schmalz, it's the successor to the popular Easy Driver board.\n\nIt defaults to 16-step microstepping mode and includes onboard 5 V and 3.3 V voltage regulators, so only a single motor supply is needed. Accepts motor drive voltages up to 30 V.\n\nSpecifications\n\n\nDriver Chip – Allegro A4988\n\nMax Current – 2 A/phase\n\nWithout Heatsink – 1.4–1.7 A/phase\n\nMax Motor Voltage – 30 V\n\nMicrostepping – Up to 1/16 step (default)\n\nOnboard Regulation – 5 V and 3.3 V\n\nMotor Type – Bipolar stepper\n\n\nKey Features\n\n\nSingle Supply – Onboard regulators eliminate need for separate logic power\n\nChopper Driver – Efficient current regulation\n\nConfigurable Microstepping – Full, half, quarter, eighth, and sixteenth step\n\n\nIdeal For\n\nCNC machines and 3D printers\nCamera sliders and pan/tilt systems\nRobotics and automation\nAny project requiring precise stepper motor control\n\n\n\nNote: A heatsink is recommended for loads approaching 2 A/phase. The board operates at 1.4–1.7 A/phase without active cooling.\n\n\nResources\n\nHookup Guide\nA4988 Datasheet (PDF)\nSchematic (PDF)\nEagle Files\nDesign Site\nGitHub Repository\n","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":12760,"title":"Default Title","sku":"SF-ROB-12859","price":42.23,"on_sale":false,"in_stock":true,"available_quantity":245,"option1":"Default Title"}]}
