Overview
The DSpower DS-SY15A is a dual-shaft metal-gear serial-bus servo for robot and mechanical-arm projects. It operates from 5.0–12.6 V DC and is rated at ≥15 kgf·cm stall torque at 7.4 V. UART communication is specified, while TTL and RS485 dual-protocol serial-bus support with real-time feedback is also stated. Its 360° operating travel and low-height square form support compact motion-system integration.
Features
- Dual-shaft metal gears and a low-height square design for installation where space is limited.
- TTL + RS485 serial-bus communication with stated real-time feedback; UART is specified as the communication interface.
- Heat-dissipation plastic casing.
- Stated anti-stall, over-current, over-temperature, and over-voltage protection.
- Listed characteristics include large torque, anti-burn and anti-shake performance, tooth-sweeping prevention, lower noise, and high precision.
- An imported potentiometer is stated with a maximum 300° rotation and a lifespan of at least 500,000 cycles.
- Communication-protocol drawings and debugging software are stated as provided.
- Marked CE, RoHS, and FCC.
