The EF90D is a compact 360° continuous rotation digital servo designed for micro:bit projects. Slightly larger than a 5-cent coin, it operates at 3V making it perfect for direct connection to micro:bit's servo pins. Speed and direction are controlled via pulse width modulation, making it ideal for small robots, mechanical arms, and intelligent car modules where continuous rotation is needed rather than position control. Key Features 360° Continuous Rotation – Full rotation for wheels and continuous motion 3V Compatible – Works directly with micro:bit PWM Speed Control – Adjust rotation speed via pulse width Compact Size – Lightweight and portable Digital Servo – Precise control with 5µs dead band Standard Connector – JR/Futaba compatible plug Specifications Model: EF90D SKU: EF09081 Rotation: 360° continuous Operating Voltage: 3.0-5.5V Torque: 1.6kg/cm Dead Band: 5µs Servo Type: Digital Connector: JR/Futaba Operating Temperature: -30°C to +60°C Materials: Plastic gears, plastic shell Ideal For micro:bit robotics projects Small robot wheels and drives Mechanical arm modules Intelligent car builds Continuous rotation applications Package Contents 1× EF90D 360° Digital Servo Mounting screws Multi-function steering wheel/horn
