1.Durable and Sturdy Exterior Design:
All Aluminum Alloy Shell+CNC Precision Manufacturing,Improve the Servo Case
Heat Resistance, Dimensional Stability, Rigidity, and Mechanical Properties;

2.Core Power 50kg Large Torque:
When the voltage is 12V, the stall torque can reach 50kg.cm, which can be used to
build quadrupeds, hexapods, and machinery
Multiple axis small volume turning projects such as arms,
humanoid robots, and simple industrial equipment give your project more degrees of freedom.

3.High Precision 360 ° Magnetic Encoder:
Adopting a 12 bit high-precision magnetic encoding angle sensor。Compared to carbon film potentiometers,
The usable angle of the magnetic encoder is expanded to 360 °,
4x increase in resolution,Can achieve a maximum of 7 turns in both forward and reverse directions,
Due to the gap between the magnetic encoder component and the radial magnet, there is no friction,
which effectively extends the service life of the servo.

4.Constant Force Control, Gripper Flexible Gripping:
Adopting innovative servo direct drive design, force position control, and setting output torque value,
The servo can maintain this torque, whether it is hard or soft, without damaging objects
Surface and precise gripping.

5.Daisy Chain Connection:
Up to 253 servos can be connected in series simultaneously,
achieving a simple wiring structure and occupying fewer ports.

6.Acceleration Start Stop Function:
Speed and acceleration values can be set for a softer motion effect,
reducing the impact force caused by inertia.

7.Closed Loop Feedback Real-time Protection:
The servo can provide real-time feedback on position, load, speed, input voltage, current, and temperature information,
When the environment changes, such as stalling or exceeding the temperature limit, unloading protection will be activated.

8.Multiple operating modes,More diverse usage scenarios:
Angle servo mode:efault this mode,0~360°Controllable angle and position;
Motor constant speed mode:Motor constant speed mode,As the load increases,Maintain speed without slowing down;
Stepping mode:Can perform step motion relative to the current position;

9.Open source control process:
Synchronous writing
Asynchronous writing
Synchronous reading
Single read
360°Full angle control
±7 Turns Anglecontrol
Stepping modecontrol
Closed loop modecontrol
Torquee limiting function
Constant force mode control

10.Full Metal Brackets:
All Aluminum Alloy Shell+CNC Precision Manufacturing,
Simplified structural development, More flexible combination use

Note:
One UART can control 253 bus servos, but due to the high power of the servos,
When using too many servos, it is necessary to consider
whether the power supply scheme can meet the requirements.
