Feetech FT90R 6V 1.5kg.cm 360° Continuous Rotation Digital Micro Servo

The Feetech FT90R is a continuous-rotation micro servo: instead of holding an angle, it spins in either direction, with the PWM signal setting direction and speed. At 6V it reaches 130 RPM with 1.5kg.cm of stall torque, making it a simple drive for small robot wheels, winches, rotating mounts and turntables.

Key features

• Clockwise from 1500µs towards 1000µs, counter-clockwise from 1500µs towards 2000µs
• 4.8–6V operation, so it runs from a common 5V or 6V servo supply
• 9g in an ABS case measuring 22.9 x 12.1 x 26.5mm
• 250mm lead with a JR connector
• 20T output spline with a POM horn

It cannot hold a set angle, so it is no substitute for a positional servo on control surfaces or tilt mounts; choose a positional servo such as the FT90M for those jobs.
