Description
The Hiwonder HTS-20L Serial Bus Servo is a high-performance digital servo designed for robotics applications that demand precise control, strong torque, and intelligent feedback.
Featuring an all-metal gear structure, 20 kg·cm torque, and multi-feedback capability (position, temperature, and voltage), this servo delivers reliable motion control for robotic arms, bionic robots, and multi-joint mechanisms.
With three connector ports for easy daisy-chain wiring, you can link multiple servos neatly in serial bus mode—ideal for large robot assemblies. The servo supports UART communication with an open bus protocol, compatible with 51-series MCUs, Arduino, and STM32 controllers. Through the provided PC debugging software, users can configure parameters such as ID, rotation speed, LED status, and protection alarms.
Key Features
• 20 kg high torque (7.4 V) with all-metal gears for durability
