UART Serial Bus Control

Allows controlling up to 253 serial bus servos at the same time

ST3025-Servo-details-5.jpg

Note: though one channel UART can control up to 253 serial bus servos, due to the high power of the servos, it is necessary to consider whether the power supply solution is enough when using too many servos. For reference only, the servo driver board is NOT included

 

Easy to use, Large Torque

Supports 6.0~12.6V Wide range Voltage Input, And Can Be Directly Powered By 3S lithium batteries. Up To 40kg.Cm Torque On 12V Voltage, Suitable For Building Quadruped Robots, Hexapod Walkers, Robotic Arms And Other Robotic Projects Requiring Multiple Servos

360° Magnetic Encoder - High Precision, Longer Lifetime

Adopts 12-bit high-precision magnetic encoding angle sensor. Compared with the carbon film potentiometer, the angle of the magnetic encoder is enlarged to 360°, and the resolution is increased by 4 times. Since there is a gap and no friction between the magnetic encoder and the radial magnet, the lifetime of the servo is effectively extended.

Multiple operation modes suitable for more application scenarios

ST3025-Servo-details-19-1.gif

Angle servo mode
Default mode, the angle position is controllable at 0~360° degrees

 

 

ST3025-Servo-details-19-2.gif

Speed closed-loop motor mode
Motor mode, intelligently control and maintain speed when the load changes

 

 

ST3025-Servo-details-19-3.gif

Step mode
Can perform step motion relative to the current position

 

 

Multi-Loop angle Position control

Supports angle position control in both positive and negative directions up to 7 loops under the default precision setting, but the number of loops will not be saved in case of power loss. Lowering the angle resolution can double the number of control loops

Supports installing flat-shaft flange

With the flat-shaft flange designed for this serial bus servo, the output shaft of the servo can be installed on more devices, making full use of various working modes and excellent low-speed performance. It can be used to install various transmission parts such as 6mm shaft couplings, wheels, timing pulleys, and gears.
