Description Mini Fan Unit is a compact power-drive unit based on an N20 DC motor. Mini Fan Unit is controlled by GPIO level or PWM signals and can deliver a no-load output shaft speed of up to 8800 RPM for precise start/stop control and stepless speed regulation. Mini Fan Unit communicates through a Grove HY2.0-4P interface and integrates drive and protection circuits for embedded motion projects. With two LEGO-compatible holes, Mini Fan Unit can be mounted with LEGO structures or screws for robot drive systems, model power, active cooling and other motion-control scenarios. Features N20 DC motor drive: Mini Fan Unit uses an N20 DC motor for compact motion and airflow projects. Up to 8800 RPM: the output shaft reaches up to 8800 RPM under no-load conditions. GPIO and PWM control: Mini Fan Unit supports precise start/stop and stepless speed regulation. Grove HY2.0-4P interface: Mini Fan Unit connects to M5Stack controllers through a standard Grove port. Single-direction rotation: designed for unidirectional fan, model power and motion-control use. LEGO-compatible mounting: Mini Fan Unit includes two LEGO-compatible holes for quick mechanical integration. Development support: examples are available for Arduino, UiFlow1 and EasyLoader testing.
