Towerpro Servo Motor - MG938 (Metal Gear)

The MG938 from TowerPro is a digital 31g metal gear, double ball bearing servo designed for RC helicopters & airplanes, but useable in just about any servo situation we can think of. The unit features a central alloy casing, and all metal gearing.

The unit features a stalling torque of 3.7kg in a 31g package, and it's larger (and heavier) than the MG90/1/2 ranges.

The unit comes complete with 32cm 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!

Wiring Guide:

  • Red: Battery Positive  
  • Brown: Battery Negative  
  • Orange: Signal

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.
