The servo can provide various feedback information: position, speed, torque lock, operating mode (servo mode, servo motor mode, etc.), suitable for advanced projects requiring closed-loop automatic control.17. Can be used to build quadruped, hexapod, robotic arm, and other robot projects requiring multiple servos (this product provides the open-source structural model of the robot dog shown in the figure below).18. Controlled via serial bus, allowing up to 253 servos to be connected in series simultaneously.19. Uses a 12-bit high-precision magnetic encoder angle sensor. Compared to potentiometers, the angle is increased to 360 degrees, and the resolution is increased by 4 times. Due to the gap between the magnetic encoder element and the radial magnet, there is no friction, effectively extending the servo's lifespan.20. Acceleration start/stop function: speed and acceleration values ??can be set for smoother motion.21. The shell uses a higher-strength engineering plastic shell and a dual-axis low-profile shell structure design, optimizing the distance between the planes where the dual-axis servo discs are located, making the overall structure more compact and the product appearance more aesthetically pleasing.22. The servo motor can provide real-time feedback on position, load, speed, and input voltage, allowing for constant monitoring.23. We have open-sourced the web-based control example for the servo motor driver board and provided a secondary development tutorial, which can be directly used for remote setting and control of the servo motor.

Only power on after confirming that everything is working properly. 2. If the remote control battery voltage is low, please replace the batteries immediately. (A low battery voltage in the remote control generally reduces the control range.) 3. When using wireless electronic products, avoid strong interference sources such as metal covers, large electronic devices, and electromagnetic fields to prevent the remote control from being too close to the receiver or causing it to malfunction. 4. Do not use this electronic product improperly. Improper use can reduce product performance and lifespan, and in severe cases, damage the product and pose a safety hazard. 5. The delay time setting is automatically set when entering learning mode. The delay time setting is linked to the number of times the learning button is pressed. Please pay special attention to this.Specification: Package Weight One Package Weight 0.07kgs / 0.15lb One Package Size 7cm * 6cm * 3cm / 2.76inch * 2.36inch * 1.18inch Qty per Carton 100 Carton Weight 5.50kgs / 12.13lb Carton Size 36cm * 25cm * 10cm / 14.17inch * 9.84inch * 3.94inch Loading Container 20GP: 2962 cartons * 100 pcs = 296200 pcs40HQ: 6878 cartons * 100 pcs = 687800 pcs
