## Description

2-axis servo motor for robotics and mechanism projects with stable movement, 0-270 degree rotation and high torque up to 22 Kg/cm at 7.2V. Offers fast and precise response, metal gears for durability and CNC milled aluminum alloy internal housing for rigidity and better heat dissipation. Compatible with Arduino and other PWM boards.
Performance servo motor with 2 axes (one controllable, the opposite one is support) with a rotation between 0 and 270 degrees and a maximum power of 22KG/cm.
The gears are made of metal and the inner casing is made of CNC-milled aluminum alloy. The response of the servomotor is fast, precise and with a large torque.
Heat dissipation is also improved.
It is compatible with Arduino and other development boards capable of generating a PWM signal. It still needs external power, the development boards not having enough power to power it.
