It offers a rotation range of 0 to 180 degrees with a stall torque of 1.2 kg·cm at 4.8V, making it a go‑to actuator for Arduino and Raspberry Pi projects. Its reliable plastic gears and standard 3‑pin connector ensure easy integration with most microcontroller platforms.\u003c\/p\u003e\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\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\u003e4.8 – 6.0 V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eStall Torque (4.8V)\u003c\/td\u003e\n\u003ctd\u003e1.2 kg·cm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOperating Speed (4.8V, no load)\u003c\/td\u003e\n\u003ctd\u003e0.12 sec \/ 60°\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eRotation Angle\u003c\/td\u003e\n\u003ctd\u003e0 – 180°\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e9 g\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDimensions (L×W×H)\u003c\/td\u003e\n\u003ctd\u003e23.1 × 12.2 × 28.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eMiniature robotic arm with 3–4 servos for precise joint movement\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-servo-pan-tilt-mount\"\u003ePan‑tilt camera mount for object tracking using OpenCV\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/automatic-pet-feeder-kit-ai-object-detection-and-4-dof-servo-arm\"\u003eAutomatic pet feeder with timed dispensing lid\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/arduino-solar-tracker-kit-with-ldr-sensors-and-servos-track-the-sun\"\u003eSolar tracker that follows the sun for small photovoltaic panels\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThe SG90 works seamlessly with any microcontroller that supports PWM output, such as Arduino Uno, Nano, Raspberry Pi (with external power), ESP32, and STM32. Its logic signal is 5V‑tolerant, and the servo can be powered directly from a 5V rail if current draw is limited. For multiple servos, pair with a dedicated servo driver like PCA9685 or an external 5–6V supply.\u003c\/p\u003e\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eConnect the brown wire to GND, red to 5V (or 4.8–6V external supply), and the orange\/yellow signal wire to any PWM‑capable GPIO pin. Use a 100–470 µF decoupling capacitor across the power rails if you notice jitter. Never power more than two servos directly from an Arduino’s 5V regulator – use a separate battery or DC adapter.\u003c\/p\u003e\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.

If defective on arrival, replace within 7 days.\u003c\/p\u003e\n\u003cdetails\u003e\u003csummary\u003eIs this compatible with Arduino?\u003c\/summary\u003e\u003cp\u003eYes, the SG90 works directly with the Arduino Servo library. Just connect the signal wire to a PWM pin (e.g., D9) and upload a sweep sketch.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eWhat is the torque at 6V?\u003c\/summary\u003e\u003cp\u003eAt 6V input, the stall torque increases to approximately 1.8 kg·cm, providing a noticeable boost for heavier loads.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eCan this servo rotate 360°?\u003c\/summary\u003e\u003cp\u003eOut of the box, the SG90 is limited to 180° by a mechanical stop. Continuous rotation requires internal modification (removing the potentiometer stop and disconnecting the feedback potentiometer).\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.
