XL330-M077-T: the lightweight successor to the Dynamixel programmable servos

With the XL330-M077-T (and its analogue XL330-M288-T ), Robotis has adapted its 100% all-in-one programmable servo model to a much lighter range in terms of price, power consumption, and weight.

The Dynamixel XL330-M077-T servomotor is a very compact version of the well-known XH or XM series.

It is ideal for applications in small or confined spaces.

Dynamixel XL330-M077-T: driving small cars

It can also be used on small radio-controlled race cars, as it supports RC protocol for remote control.

With its very high no-load speed (up to 363 rpm) and high resolution, it is ideal for high-speed driving, especially since its various operating modes include PWM control.
