Features

The FT90R is a micro-sized digital servo continuous rotation. At 6 V, it has a maximum rotation speed of around 170 RPM (no-load) and can produce up to 21 oz-in (1.5 kg-cm) of torque. The servo can be controlled using a direct connection to a single microcontroller I/O line without any additional electronics, which makes it a great miniature actuator for beginner robotics projects; just throw on a pair of wheels and your robot is ready to roll!

The FT90R continuous rotation servo converts standard RC servo position pulses into continuous rotation speed. The rest point is set precisely to 1.5 ms with a deadband width of ±20 µs. Pulse widths above the rest point result in counterclockwise rotation, with speed increasing as the pulse width increases; pulse widths below the rest point result in clockwise rotation, with speed increasing as the pulse width decreases.

Wheel

This black plastic wheel is press-fit onto the FS90R output gear shaft, and easy to make a nice drive solution for small robots. The wheels have silicone tires and measure 60 mm (2.36″) in diameter. Two additional mounting holes for 3-40 screws make it possible to use the wheel with several of mounting hubs.
