2.3kg Serial Bus Servo, Two-way Feedback

Easily control up to 253 serial bus servos through a single UART channel—perfect for complex robotics or automation projects. Just a heads-up: while you can technically run that many servos, make sure your power supply can keep up! (Power-hungry servos can drain fast.) Note: Servo driver board not included.

Enjoy smooth 300° rotation for precise angular control in Servo mode, making it great for applications that demand flexibility and accuracy.

Built with a smart combo of high-precision copper and steel gears, this setup keeps operating noise low while delivering excellent mechanical stability and performance.

And with real-time two-way feedback, you get live updates on position, load, speed, and input voltage—so you're always in the loop.
