The Futaba S3003 Servo Motor 3.2Kg/cm Torque is a great multi-purpose standard-size high reliability servo, and it can be easily modified for continuous rotation. Features plastic gearing, so these are not suitable for high impact applications, but they’re a great choice for beginners – perfect for moving a robotic arms through a certain range or steering a rover! We do stock metal geared, high torque servo’s for more intensive applications. The unit comes complete with 30cm wire and 3 pin ‘S’ type female header connector that fits most receivers. This servo can rotate approximately 180 degrees (90 in each direction), but can be modified for full rotation, and comes with a range of horns and hardware to suit most applications! 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. They work great with 16 Channel Servo Driver , and other Raspberry Pi Motor Controllers.
