3.7V to 5V 7V 9V Boost Board Fan Motor Speed Controller Board USB Rechargeable Fan Circuit Board Governor Step Up Module Feature: 1. Compact design: The control board adopts a miniaturized design, making it suitable for installation in devices with limited space. 2. Boost conversion function: The built-in boost circuit can boost from a lower battery voltage (such as a 3.7V lithium battery) to 5V, 7V or 9V to meet the working requirements of the fan motor. 3. Low standby current: In standby mode, the control board has an extremely low current consumption (such as 10uA), which helps to extend the battery life of the device. 4. Multi-voltage output support: The boost board can boost the battery voltage to multiple output voltages such as 5V, 7V, 9V, etc., suitable for fans with different power requirements. 5. Wide range of use: This type of control board is widely used in small handheld fans powered by lithium batteries. It has the advantages of high integration and low cost, and is suitable for the design requirements of portable devices.
