Overview
The Feetech HD-1910-C001 is a compact coreless metal gear servo for Microduck-style DIY robot mechanisms, small articulated joints, and other space-conscious robotics projects. It uses a TTL serial-bus interface with a 3-pin connector, a dual-shaft structure, and multiple mounting points for compact actuator integration.
The listed motor option provides 10 kg.cm stall torque and operates at 5-8.4 V. Confirm the required power, communication settings, mechanical fit, travel range, and thermal performance on the supplied unit before system integration.
Key Features
- Coreless hollow-cup motor architecture for compact robotic-joint packaging
- Metal gear train
- TTL serial-bus interface with a 3-pin connector
- Dual-shaft output structure
- 10 kg.cm listed stall torque for initial actuator sizing
- 5-8.4 V listed operating voltage
- Compact body with multi-point and multi-hole mounting
- Suitable for evaluating Microduck-style biped and articulated-robot mechanisms

Integration Notes
- Evaluate mechanical fit, power requirements, protocol, calibration, and controller compatibility before using the servo in a Microduck build.
- The 10 kg.cm specification is a stall-torque figure, not a continuous-load rating. Size the power supply and wiring for the actual dynamic load.
- Verify the exact bus protocol, servo ID configuration, baud rate, and host-controller compatibility before connecting multiple actuators.
- The Feetech URT2 Test Board is a separately selectable option and is not included with the HD-1910-C001 Motor option.
