説明
Small machines are not small ambitions. The SG90 is the quiet workhorse behind a thousand builds: robot arms that reach, camera gimbals that steady, wings that turn, and doors that open on command.
The Micro Grip delivers genuine SG90 9G micro servos in flexible lot sizes, from a two-pack for a weekend project to fifty for a classroom or a production run. Each unit turns a claimed 180 degrees with a plastic gear train that is light enough for micro airframes and tough enough for daily bench abuse.
Consistency matters when you are building twenty identical joints. These servos are tested to hold position under load, center reliably, and respond to standard 50Hz PWM signals from Arduino, Raspberry Pi, and any hobby receiver.
Give a small motor a clear signal, and it will move the world in small, precise increments.
Because these servos are sold in lots, they also make economic sense: a 20-pack for a walking robot project, a 50-pack for a university lab that burns through actuators every semester. Each unit is the same spec, so your jig and your code stay valid across the whole batch.

Frequently Asked Questions
Q: What voltage should I run?
A: The servo operates across 4.8V-6V. Most Arduino boards at 5V are fine; for higher torque, a regulated 6V supply works well.
Q: Does it work with Arduino and Raspberry Pi?
A: Yes. Any device that can generate a standard 50Hz PWM signal with a 1-2ms pulse can drive it. Arduino Servo.h works out of the box.
Q: How much torque does one servo provide?
A: Roughly 1.8 kg-cm at 4.8V, which is enough for light control surfaces, small arms, and camera gimbals. For heavier loads, step up to a metal-gear servo.
Q: Are the mounting arms included?
A: Each servo ships with screw-on horns and mounting hardware, so you can bolt it into your build immediately.
Q: Do the servos center reliably?
A: They are checked to hold position and center consistently, which matters when a build uses several servos that must agree with each other.
The EastSupplier Promise
Every product in our catalog is sourced directly from vetted manufacturing partners, inspected before dispatch, and shipped with tracking. If anything arrives damaged or does not match its listing, our support team responds within 24 hours with a replacement or a full refund. No forms, no waiting, no fine print.






Q: What PWM frequency should I use?
A: Standard hobby servos expect a 50Hz frame rate with a pulse between 1ms and 2ms. Arduino Servo.h and most RC receivers already output this, so no extra configuration is needed.
Q: Do these work for FPV camera gimbals?
A: For small FPV and action-camera gimbals, the SG90 is a common starting point because of its low weight. For heavier camera rigs you will want a metal-gear servo with higher torque.
Q: Do they come with the arms and screws?
A: Yes, every servo ships with its screw-on horn set and mounting screws. The JR-style connector plugs directly into standard hobby receivers and servo extension cables.
Q: Can I use them for continuous rotation?
A: The standard SG90 is a 180-degree positional servo. For continuous rotation you would need to modify it or use a dedicated continuous-rotation variant; this listing is the classic positional model.
