## Description

An ultra-compact 2.5g micro servo with 360-degree continuous rotation, ideal for micro robots and space-constrained projects. The coreless motor and POM gears deliver smooth, reliable rotation in a tiny form factor measuring just 19.6 × 8.0 × 16.3mm. Controlled via standard PWM servo signals, it connects directly to an Arduino output pin without a motor driver. Write 0° for full-speed clockwise, 90° to stop, and 180° for full-speed counterclockwise using the Arduino Servo library. Key Features 360° Continuous Rotation – Full rotational motion with speed and direction control via PWM Ultra-Lightweight – Only 2.9g, perfect for micro robots and lightweight builds Coreless Motor – Smooth operation with MOSFET driver Standard PWM Control – 50Hz, 900–2100µs pulse width, 1500µs midpoint POM Gears – Durable engineering plastic gears Specifications Model – D2S51 Voltage – 4.8–6.0V DC Speed (no load) – 0.09 sec/60° at 4.8V, 0.07 sec/60° at 6.0V Torque (stall) – 0.45 kg·cm at 4.8V, 0.60 kg·cm at 6.0V Working Current – <0.10A at 4.8V, <0.10A at 6.0V Stall Current – <0.5A at 4.8V, <0.5A at 6.0V Dimensions – 19.6 × 8.0 × 16.3mm Weight – 2.9g Operating Temperature – -20°C to 60°C Ideal For Micro robots and miniature motorised builds Projects with tight space constraints Arduino-controlled continuous rotation applications Package Contents 1× Micro servo (D2S51) 4× Servo horns (assorted shapes) 2× Mounting screws 2× Servo horn attachment screws Warning: Do not exceed 6.0V — higher voltages will permanently damage the servo. Avoid stalling the servo as the gears may break. Do not remove the plastic strap holding the upper and lower casing together. Note: This is a continuous rotation servo — it cannot hold a specific angular position like a standard servo. Control speed and direction only.
