Περιγραφή
Χαρακτηριστικά

This product is a dual-axis serial bus servo with high torque. It incorporates a 360° high-precision magnetic encoder, allowing for angle control within a 360° range. The case is manufactured using high-precision CNC machining techniques. It is driven by a brushless motor, significantly increasing its lifespan and reliability. Supports 6.0-12.6V wide range voltage Input, and can be directly powered by 3S lithium batteries. You can use this servo driver board (NOT included) to control the bus servo.

Application examples

Servos will provide various feedback like load, position, speed, input voltage, working current, working mode (servo mode, servo motor mode, etc.) for advanced projects requiring closed-loop automatic control.
Ideal choice for building quadruped robots, hexapod walkers, robotic arms and other robotic projects requiring multiple servos. (This product provides open source models)

UART serial bus control

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

360° magnetic encoder for high precision and 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

Angle servo mode: Default mode, the angle position is controllable at 0-360° degrees.
Speed closed-loop motor mode: Motor mode, intelligently control and maintain speed when the load changes.
Step mode: Can perform step motion relative to the current position.

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.

Open Source Control Program

Open-source web control demo of the servo driver board is provided and also a secondary development tutorial, which can be directly used for remote setting and remote control of the servo. At the same time, we also provide a 3D model for you to build your project quickly.

One button to calibrate the middle position

360° installation at any position, one button to set the current position as middle 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.

Acceleration Start-stop Function

The speed and acceleration values are settable to make the motion effect softer
