Details
The L3025 belongs to MUWEIDU’s low-speed, high-precision mini servo motor lineup with a hollow-shaft form factor for compact integration.
Core design elements focus on torque in tight spaces, smooth rotation, and accurate current sampling for stable speed/position control.
Wiring is simplified with clearly labeled power, RS485 A/B, UART TX/RX, signal ground, plus an onboard ID switch for multi-device setups.
PC-side tools support parameter tuning, testing, and firmware updates, with multiple control modes available depending on configuration.
A compact servo form factor suits precision motion tasks such as gimbals, camera modules, and LiDAR/robot sensing platforms.
