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.
