Towerpro Servo Motor - SG90 Digital

Towerpro Servo Motor - SG90 Digital
Sold Out
£ 4.00

The SG90 from TowerPro is the most popular 9g servo in the world. This is the digital version! The unit features a stalling torque of 1.8kg in a tiny 9g micro package.

The unit comes complete with 25cm wire and 3 pin 'S' type female header connector that fits most receivers, including Futaba, JR, GWS, Cirrus, Blue Bird, Blue Arrow, Corona, Berg, Spektrum and Hitec.

They work great with our UltraBorg servo and ultrasonic control board, and other Raspberry Pi Motor Controllers. They're also great for the Arduino Motor Shield - or simply by wiring up Arduino with the Servo library. You can use any servo code, hardware or library to control these servos, so it's great 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.

Towerpro Servo's comes with a selection of arms and hardware to get you set up nice and fast!

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 (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.
