The REES52 SG90 servo motor is a small, lightweight servo. The 9g mini servo is compatible with most standard remote systems and with Arduino, Futaba, JR, Hitec, Sanwa and GWS.
The listing describes a high-torque 180-degree servo designed for a wide range of applications, including RC aircraft, cars and robotics.
It is presented as a high-quality, cost-effective servo that suits fixed wings, helicopters, KT boards, gliders, small robots, robotic arms and other models.
High quality, good value: a budget servo for many projects.
Small and lightweight: 9g.
Wide compatibility: Arduino, Futaba, JR, Hitec, Sanwa, GWS and most standard remotes.
180 degree rotation: standard position servo.
Wide voltage: 3.0 to 7.2V DC.
Broad use: fixed wings, helicopters, gliders, small robots and robotic arms.
A hobby servo combines a small motor, a gearbox and a position sensor with control electronics. You send it a pulse every 20 milliseconds or so, and the width of the pulse tells it where to go: about 1.5 milliseconds is centre, with roughly 1.0 and 2.0 milliseconds at the ends. The servo drives its output shaft until the sensor says it has reached the commanded position, then holds it against the load.
Digital servos process the signal with a microcontroller and drive the motor at a much higher rate than analogue servos, which gives faster response, a smaller dead band and stronger holding torque. Metal gears cope better with shock loads than plastic ones, and ball bearings keep the shaft smooth and reduce wear.
Always power a servo from a supply that can deliver its peak current, not from a weak receiver port, and keep the linkage free so the servo never strains against a mechanical stop. A stalled servo draws a large current and can overheat within seconds.

The specification list gives a model of SG90, nylon gears, an analog controller, an operating voltage of 3.0 to 7.2V DC, an operating temperature of -30 to 60 degrees C, a dead band width of 7 microseconds, a 180-degree range, a weight of 9 grams and a blue colour.
Because the gears are nylon, keep loads light and avoid stalling the servo against a stop.
