It is commonly used in wearable devices, mobile phones, and DIY haptic feedback systems. Its small size and low power consumption make it ideal for embedded electronics projects.\u003c\/p\u003e\u003ch2\u003eKey Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e3V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated Current\u003c\/td\u003e\n\u003ctd\u003e60mA (typ), 100mA max\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNo-load Speed\u003c\/td\u003e\n\u003ctd\u003e12,000 ± 2,500 RPM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiameter\u003c\/td\u003e\n\u003ctd\u003e10mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThickness\u003c\/td\u003e\n\u003ctd\u003e2.7mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLead Wire Length\u003c\/td\u003e\n\u003ctd\u003eApprox. 30mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eHaptic feedback gloves for virtual reality\u003c\/li\u003e\n\u003cli\u003eDIY game controller with vibration alerts\u003c\/li\u003e\n\u003cli\u003eSilent notification band for IoT projects\u003c\/li\u003e\n\u003cli\u003eWearable timer or medication reminder\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCompatibility\u003c\/h2\u003e\u003cp\u003eThis motor operates at 3V and draws up to 100mA, making it compatible with 3.3V boards like ESP32 and Raspberry Pi Pico, as well as 5V Arduino boards with a current-limiting resistor or transistor driver. Pair it with an NPN transistor (e.g., 2N2222) and flyback diode for safe GPIO control.\u003c\/p\u003e\u003ch2\u003eWiring Notes\u003c\/h2\u003e\u003cp\u003eConnect red wire to positive supply (3V) and black to ground. To control from a microcontroller pin, use a transistor to handle the motor current, as most GPIO pins cannot source more than 20-40mA. Always add a flyback diode across the motor terminals to protect against voltage spikes.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.\u003c\/p\u003e\u003cdetails\u003e\u003csummary\u003eIs this compatible with Arduino Uno?\u003c\/summary\u003e\u003cp\u003eYes, but you must use a transistor or motor driver circuit since the Arduino pin cannot supply enough current. Connect the base of an NPN transistor through a resistor to the pin, and run the motor from the 5V supply.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eCan I power it directly from a 3.7V LiPo battery?\u003c\/summary\u003e\u003cp\u003eYes, the motor can handle up to 4V intermittently. For continuous use, a small series resistor or PWM duty cycle reduction is recommended to stay near the rated 3V.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eHow strong is the vibration?\u003c\/summary\u003e\u003cp\u003eAt 3V, the vibration is noticeable but mild—similar to a smartphone on silent. It is suitable for subtle haptic alerts, not for massaging applications.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
