Micro Servo – SG90


Micro Servo – SG90



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.

Please note, this servo will ‘hold’ the position even when no signal is sent!

To control with an Arduino, we suggest connecting the orange control wire to pin 9 or 10 and using the Servo library included with the Arduino IDE (see here for an example sketch). Position “0” (1.5ms pulse) is middle, “90” (~2ms pulse) is all the way to the right, “-90” (~1ms pulse) is all the way to the left.
