{"product_id":"reprap-a4988-stepper-motor-driver-3d-printer-heat-sink-with-sticker","title":"Reprap A4988 stepper motor driver 3D Printer + heat sink with sticker","description":"The A4988 driver Stepper Motor Driver is a complete micro-stepping motor driver with a built-in converter, easy to operate. It operates from 8 V to 35 V and can deliver up to approximately 1 A per phase without a heat sink or forced air flow (it is rated for 2 A per coil with sufficient additional cooling).\u003cbr\u003e\u003cbr\u003eA4988 driver Stepper Motor Driver includes a fixed off-time current regulator, the regulator can be in slow or mixed decay mode. The converter is the key to the easy implementation of the A4988.\u003cbr\u003e\u003cbr\u003eThere are no phase sequence tables, high-frequency control interface programming, etc. The application of the A4988 interface is very suitable for a complex microprocessor that is not available or overloaded. In the stepping operation, the chopping control in the A4988 automatically selects the current decay mode (slow or mixed). The mixed decay current control scheme can reduce the audible motor noise, increase step accuracy, and reduce power consumption.\u003cbr\u003e\u003cbr\u003eProvide internal synchronous rectification control circuitry, to improve the pulse width modulation (PWM) power consumption during operation. \u003cbr\u003e\u003cbr\u003eInternal circuit protection includes thermal shutdown with hysteresis, under-voltage lockout (UVLO), and crossover current protection. Don’t need special power-up sequencing. A4988 uses a surface mount QFN package (ES), the size is 5 mm × 5 mm, nominal overall package height is 0.90 mm, with an exposed thermal pad to enhance the heat dissipation function.\n\u003cdiv class=\"product_info\"\u003e\n\u003ch1 class=\"sing--sub-heading\"\u003e\u003cspan style=\"font-size: 18.72px;\"\u003e Features:\u003c\/span\u003e\u003c\/h1\u003e\n\u003cstrong\u003eA4988 Driver Chip:\u003c\/strong\u003e Provides precise control of stepper motors with microstepping capabilities.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eHeat Sink:\u003c\/strong\u003e Includes a heat sink to ensure efficient cooling and prevent overheating during operation.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSticker for Identification:\u003c\/strong\u003e Comes with a sticker for easy labeling and organization of components.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eCompact Design:\u003c\/strong\u003e Space-efficient design suitable for integration into tight spaces within 3D printers and other devices.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eHigh Current Capability: \u003c\/strong\u003eSupports stepper motors with high current requirements for reliable performance.\n\u003cdiv\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch2 class=\"sing--sub-heading\"\u003e\u003cspan style=\"font-size: 18.72px;\"\u003e Applications:\u003c\/span\u003e\u003c\/h2\u003e\n\u003cstrong\u003e3D Printers:\u003c\/strong\u003e Ideal for upgrading or replacing stepper motor drivers in 3D printers for better motor control and reliability.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eCNC Machines:\u003c\/strong\u003e Suitable for use in CNC machines to manage stepper motors with improved cooling.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eRobotic Projects:\u003c\/strong\u003e Enhances performance in various robotic systems requiring precise stepper motor control.\n\u003cdiv\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eTechnical Details\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eOperating Voltage (VDC): 8 ~ 35\u003c\/li\u003e\n\u003cli\u003eCurrent (No Hestsink): 1 A\u003c\/li\u003e\n\u003cli\u003eCurrent (With Hestsink): 2 A\u003c\/li\u003e\n\u003cli\u003eLogic Input (V) : 3 ~ 5.5\u003c\/li\u003e\n\u003cli\u003eCharacters: 16\u003c\/li\u003e\n\u003cli\u003eCharacter Color: White\u003c\/li\u003e\n\u003cli\u003eBacklight: Blue\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eIntegration with Arduino\u003c\/h3\u003e\n\u003cdiv style=\"text-align: start;\" id=\"p_info\"\u003e\u003cimg style=\"float: none;\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/files\/A4988-Arduino-stepper-motor-wiring-schematic-diagram-pinout-1024x551.jpg?v=1640151510\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eSample Code\u003c\/h3\u003e\n\u003cscript src=\"https:\/\/gist.github.com\/labsguru\/6b2a52ce3807a7fbf390c70cd8a4140e.js\"\u003e\u003c\/script\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eAdditional Details\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eAutomatic current decay mode detection\/choice.\u003c\/li\u003e\n\u003cli\u003eMixed with slow current decay mode.\u003c\/li\u003e\n\u003cli\u003eThe low power dissipation of synchronous rectifier.\u003c\/li\u003e\n\u003cli\u003eInternal UVLO(ultra voltage lockout).\u003c\/li\u003e\n\u003cli\u003eCrossover current protection.\u003c\/li\u003e\n\u003cli\u003eThermal shutdown circuit.\u003c\/li\u003e\n\u003cli\u003eGround fault protection.\u003c\/li\u003e\n\u003cli\u003eLoading and short circuit protection.\u003c\/li\u003e\n\u003cli\u003eThe optional five-step mode: full, 1\/2, 1\/4, 1\/8 and 1\/16.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eProduct Video\u003c\/h3\u003e\n\u003cdiv id=\"p_video\"\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/psI3aN0A-OA\" height=\"400\" width=\"800\" allowfullscreen=\"\" allow=\"accelerometer;
