SG90S 180 Degree Micro Servo

SG90S 180 Degree  Micro Servo It uses a Metal Gear drive and is light and compact. They can rotate approximately 180 degrees (90 in each direction), It can be used for various applications and DIY products.

These servo’s operation is more similar to a DC motor than a standard servo as only rotation direction and speed can be controlled. There is also no hardware stop inside so that the shaft can rotate freely. Compared to an ordinary DC motor, these servo motor does not require additional motor drivers and is plug and play, compact and convenient. Arduino control methods are also the same.

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. It can be used as continuous rotation servo motor by adding an external driver board.

These servos are static at a 1.5ms pulse, a longer pulse gives forward rotation and a shorter pulse give backward rotation.
