SG90 9 g Micro Servo Tiny and lightweight with high output power. Servo can rotate approximately 180 degrees (90 in each direction), and works just like the standard kinds but smaller. You can use any servo code, hardware or library to control these servos. Good for beginners who want to make stuff move without building a motor controller with feedback & gear box, especially since it will fit in small places. It comes with a 3 horns (arms) and hardware.

Hobbyists from around the world has used the SG90 on famous planes like GWS Slow Stick, E-Flite Airplanes, Great Planes, Thunder Tiger, Align, EDF jets and more. If you are looking for a servo that won't break your arm or leg, this is the perfect choice for you! The TP SG90 servo weighs 0.32 ounces (9 .0 grams) . Total weight with wire and connector is 0.37 ounces (10 .6 grams) . The TP SG90 has the universal "S" type connector that fits most receivers, including Futaba, JR, GWS, Cirrus, Blue Bird, Blue Arrow, Corona, Berg and Hitec.

FAQs

What rotation range does the SG90 micro servo support?

It can rotate approximately 180°, with about 90° in each direction from the center position.

What control signal details are listed for the SG90?

The datasheet notes a pulse cycle of about 20 ms and a pulse width range of roughly 500–2400 µs, with position mapping such as 0 at ~1.5 ms, 90 at ~2 ms, and -90 at ~1 ms.

What are the key electrical specifications and dead-band width?

It lists an operating voltage around 4.8 V (~5 V), operating speed around 0.1 s/60°, a dead-band width of 10 µs (and variants such as 7 µs), and temperature operation from about 0 °C to 55 °C.
